How well do you know your project? Years of experiments, analysis of results, and tons of literature study, leads you to how well you know your research study. And, PhD dissertation defense is a finale to your PhD years. Often, researchers question how to excel at their thesis defense and spend countless hours on it. Days, weeks, months, and probably years of practice to complete your doctorate, needs to surpass the dissertation defense hurdle.

In this article, we will discuss details of how to excel at PhD dissertation defense and list down some interesting tips to prepare for your thesis defense.

What Is Dissertation Defense?

Dissertation defense or Thesis defense is an opportunity to defend your research study amidst the academic professionals who will evaluate of your academic work. While a thesis defense can sometimes be like a cross-examination session, but in reality you need not fear the thesis defense process and be well prepared.

What are the expectations of committee members.

Choosing the dissertation committee is one of the most important decision for a research student. However, putting your dissertation committee becomes easier once you understand the expectations of committee members.

The basic function of your dissertation committee is to guide you through the process of proposing, writing, and revising your dissertation. Moreover, the committee members serve as mentors, giving constructive feedback on your writing and research, also guiding your revision efforts.

The dissertation committee is usually formed once the academic coursework is completed. Furthermore, by the time you begin your dissertation research, you get acquainted to the faculty members who will serve on your dissertation committee. Ultimately, who serves on your dissertation committee depends upon you.

Some universities allow an outside expert (a former professor or academic mentor) to serve on your committee. It is advisable to choose a faculty member who knows you and your research work.

How to Choose a Dissertation Committee Member?

  • Avoid popular and eminent faculty member
  • Choose the one you know very well and can approach whenever you need them
  • A faculty member whom you can learn from is apt.
  • Members of the committee can be your future mentors, co-authors, and research collaborators. Choose them keeping your future in mind.

How to Prepare for Dissertation Defense?

1. Start Your Preparations Early

Thesis defense is not a 3 or 6 months’ exercise. Don’t wait until you have completed all your research objectives. Start your preparation well in advance, and make sure you know all the intricacies of your thesis and reasons to all the research experiments you conducted.

2. Attend Presentations by Other Candidates

Look out for open dissertation presentations at your university. In fact, you can attend open dissertation presentations at other universities too. Firstly, this will help you realize how thesis defense is not a scary process. Secondly, you will get the tricks and hacks on how other researchers are defending their thesis. Finally, you will understand why dissertation defense is necessary for the university, as well as the scientific community.

3. Take Enough Time to Prepare the Slides

Dissertation defense process harder than submitting your thesis well before the deadline. Ideally, you could start preparing the slides after finalizing your thesis. Spend more time in preparing the slides. Make sure you got the right data on the slides and rephrase your inferences, to create a logical flow to your presentation.

4. Structure the Presentation

Do not be haphazard in designing your presentation. Take time to create a good structured presentation. Furthermore, create high-quality slides which impresses the committee members. Make slides that hold your audience’s attention. Keep the presentation thorough and accurate, and use smart art to create better slides.

5. Practice Breathing Techniques

Watch a few TED talk videos and you will notice that speakers and orators are very fluent at their speech. In fact, you will not notice them taking a breath or falling short of breath. The only reason behind such effortless oratory skill is practice — practice in breathing technique.

Moreover, every speaker knows how to control their breath. Long and steady breaths are crucial. Pay attention to your breathing and slow it down. All you need I some practice prior to this moment.

6. Create an Impactful Introduction

The audience expects a lot from you. So your opening statement should enthrall the audience. Furthermore, your thesis should create an impact on the members; they should be thrilled by your thesis and the way you expose it.

The introduction answers most important questions, and most important of all “Is this presentation worth the time?” Therefore, it is important to make a good first impression , because the first few minutes sets the tone for your entire presentation.

7. Maintain Your Own List of Questions

While preparing for the presentation, make a note of all the questions that you ask yourself. Try to approach all the questions from a reader’s point of view. You could pretend like you do not know the topic and think of questions that could help you know the topic much better.

The list of questions will prepare you for the questions the members may pose while trying to understand your research. Attending other candidates’ open discussion will also help you assume the dissertation defense questions.

8. Practice Speech and Body Language

After successfully preparing your slides and practicing, you could start focusing on how you look while presenting your thesis. This exercise is not for your appearance but to know your body language and relax if need be.

Pay attention to your body language. Stand with your back straight, but relax your shoulders. The correct posture will give you the feel of self-confidence. So, observe yourself in the mirror and pay attention to movements you make.

9. Give Mock Presentation

Giving a trial defense in advance is a good practice. The most important factor for the mock defense is its similarity to your real defense, so that you get the experience that prepares for the actual defense.

10. Learn How to Handle Mistakes

Everyone makes mistakes. However, it is important to carry on. Do not let the mistakes affect your thesis defense. Take a deep breath and move on to the next point.

11. Do Not Run Through the Presentation

If you are nervous, you would want to end the presentation as soon as possible. However, this situation will give rise to anxiety and you will speak too fast, skipping the essential details. Eventually, creating a fiasco of your dissertation defense .

12. Get Plenty of Rest

Out of the dissertation defense preparation points, this one is extremely important. Obviously, sleeping a day before your big event is hard, but you have to focus and go to bed early, with the clear intentions of getting the rest you deserve.

13. Visualize Yourself Defending Your Thesis

This simple exercise creates an immense impact on your self-confidence. All you have to do is visualize yourself giving a successful presentation each evening before going to sleep. Everyday till the day of your thesis defense, see yourself standing in front of the audience and going from one point to another.

This exercise takes a lot of commitment and persistence, but the results in the end are worth it. Visualization makes you see yourself doing the scary thing of defending your thesis.

If you have taken all these points into consideration, you are ready for your big day. You have worked relentlessly for your PhD degree , and you will definitely give your best in this final step.

Preparing For Your Dissertation Defense

13 Key Questions To Expect In The Viva Voce

By: Derek Jansen (MBA) & David Phair (PhD) . Reviewed By: Dr Eunice Rautenbach | June 2021

Preparing for your dissertation or thesis defense (also called a “viva voce”) is a formidable task . All your hard work over the years leads you to this one point, and you’ll need to defend yourself against some of the most experienced researchers you’ve encountered so far.

It’s natural to feel a little nervous.

In this post, we’ll cover some of the most important questions you should be able to answer in your viva voce, whether it’s for a Masters or PhD degree. Naturally, they might not arise in exactly the same form (some may not come up at all), but if you can answer these questions well, it means you’re in a good position to tackle your oral defense.

Dissertation and thesis defense 101

Viva Voce Prep: 13 Essential Questions

  • What is your study about and why did you choose to research this in particular?
  • How did your research questions evolve during the research process?
  • How did you decide on which sources to include in your literature review?
  • How did you design your study and why did you take this approach?
  • How generalisable and valid are the findings?
  • What were the main shortcomings and limitations created by your research design?
  • How did your findings relate to the existing literature?
  • What were your key findings in relation to the research questions?
  • Were there any findings that surprised you?
  • What biases may exist in your research?
  • How can your findings be put into practice?
  • How has your research contributed to current thinking in the field?
  • If you could redo your research, how would you alter your approach?

#1: What is your study about and why did you choose to research this in particular?

This question, a classic party starter, is pretty straightforward.

What the dissertation or thesis committee is assessing here is your ability to clearly articulate your research aims, objectives and research questions in a concise manner. Concise is the keyword here – you need to clearly explain your research topic without rambling on for a half-hour. Don’t feel the need to go into the weeds here – you’ll have many opportunities to unpack the details later on.

In the second half of the question, they’re looking for a brief explanation of the justification of your research. In other words, why was this particular set of research aims, objectives and questions worth addressing? To address this question well in your oral defense, you need to make it clear what gap existed within the research and why that gap was worth filling.

#2: How did your research questions evolve during the research process?

Good research generally follows a long and winding path . It’s seldom a straight line (unless you got really lucky). What they’re assessing here is your ability to follow that path and let the research process unfold.

Specifically, they’ll want to hear about the impact that the literature review process had on you in terms of shaping the research aims, objectives and research questions . For example, you may have started with a certain set of aims, but then as you immersed yourself in the literature, you may have changed direction. Similarly, your initial fieldwork findings may have turned out some unexpected data that drove you to adjust or expand on your initial research questions.

Long story short – a good defense involves clearly describing your research journey , including all the twists and turns. Adjusting your direction based on findings in the literature or the fieldwork shows that you’re responsive , which is essential for high-quality research.

You will need to explain the impact of your literature review in the defense

#3: How did you decide on which sources to include in your literature review?

A comprehensive literature review is the foundation of any high-quality piece of research. With this question, your dissertation or thesis committee are trying to assess which quality criteria and approach you used to select the sources for your literature review.

Typically, good research draws on both the seminal work in the respective field and more recent sources . In other words, a combination of the older landmark studies and pivotal work, along with up-to-date sources that build on to those older studies. This combination ensures that the study has a rock-solid foundation but is not out of date.

So, make sure that your study draws on a mix of both the “classics” and new kids on the block, and take note of any major evolutions in the literature that you can use as an example when asked this question in your viva voce.

#4: How did you design your study and why did you take this approach?

This is a classic methodological question that you can almost certainly expect in some or other shape.

What they’re looking for here is a clear articulation of the research design and methodology, as well as a strong justification of each choice . So, you need to be able to walk through each methodological choice and clearly explain both what you did and why you did it. The why is particularly important – you need to be able to justify each choice you made by clearly linking your design back to your research aims, objectives and research questions, while also taking into account practical constraints.

To ensure you cover every base, check out our research methodology vlog post , as well as our post covering the Research Onion .

You have to justify every choice in your dissertation defence

#5: How generalizable and valid are the findings?

This question is aimed at specifically digging into your understanding of the sample and how that relates to the population, as well as potential validity issues in your methodology.

To answer question this well, you’ll need to critically assess your sample and findings and consider if they truly apply to the entire population, as well as whether they assessed what they set out to. Note that there are two components here – generalizability and validity . Generalizability is about how well the sample represents the population. Validity is about how accurately you’ve measured what you intended to measure .

To ace this part of your dissertation defense, make sure that you’re very familiar with the concepts of generalizability , validity and reliability , and how these apply to your research. Remember, you don’t need to achieve perfection – you just need to be aware of the strengths and weaknesses of your research (and how the weaknesses could be improved upon).

#6: What were the main shortcomings and limitations created by your research design?

This question picks up where the last one left off.

As I mentioned, it’s perfectly natural that your research will have shortcomings and limitations as a result of your chosen design and methodology. No piece of research is flawless. Therefore, a good dissertation defense is not about arguing that your work is perfect, but rather it’s about clearly articulating the strengths and weaknesses of your approach.

To address this question well, you need to think critically about all of the potential weaknesses your design may have, as well as potential responses to these (which could be adopted in future research) to ensure you’re well prepared for this question. For a list of common methodological limitations, check out our video about research limitations here .

#7: How did your findings relate to the existing literature?

This common dissertation defense question links directly to your discussion chapter , where you would have presented and discussed the findings in relation to your literature review.

What your dissertation or thesis committee is assessing here is your ability to compare your study’s findings to the findings of existing research . Specifically, you need to discuss which findings aligned with existing research and which findings did not. For those findings that contrasted against existing research, you should also explain what you believe to be the reasons for this.

As with many questions in a viva voce, it’s both the what and the why that matter here. So, you need to think deeply about what the underlying reasons may be for both the similarities and differences between your findings and those of similar studies.

Your dissertation defense needs to compare findings

#8: What were your key findings in relation to the research questions?

This question is similar to the last one in that it too focuses on your research findings. However, here the focus is specifically on the findings that directly relate to your research questions (as opposed to findings in general).

So, a good way to prepare for this question is to step back and revisit your research questions . Ask yourself the following:

  • What exactly were you asking in those questions, and what did your research uncover concerning them?
  • Which questions were well answered by your study and which ones were lacking?
  • Why were they lacking and what more could be done to address this in future research?

Conquering this part dissertation defense requires that you focus squarely on the research questions. Your study will have provided many findings (hopefully!), and not all of these will link directly to the research questions. Therefore, you need to clear your mind of all of the fascinating side paths your study may have lead you down and regain a clear focus on the research questions .

#9: Were there any findings that surprised you?

This question is two-pronged.

First, you should discuss the surprising findings that were directly related to the original research questions . Going into your research, you likely had some expectations in terms of what you would find, so this is your opportunity to discuss the outcomes that emerged as contrary to what you initially expected. You’ll also want to think about what the reasons for these contrasts may be.

Second, you should discuss the findings that weren’t directly related to the research questions, but that emerged from the data set . You may have a few or you may have none – although generally there are a handful of interesting musings that you can glean from the data set. Again, make sure you can articulate why you find these interesting and what it means for future research in the area.

What the committee is looking for in this type of question is your ability to interpret the findings holistically and comprehensively , and to respond to unexpected data. So, take the time to zoom out and reflect on your findings thoroughly.

Discuss the findings in your defense

#10: What biases may exist in your research?

Biases… we all have them.

For this question, you’ll need to think about potential biases in your research , in the data itself but also in your interpretation of the data. With this question, your committee is assessing whether you have considered your own potential biases and the biases inherent in your analysis approach (i.e. your methodology). So, think carefully about these research biases and be ready to explain how these may exist in your study.

In an oral defense, this question is often followed up with a question on how the biases were mitigated or could be mitigated in future research. So, give some thought not just to what biases may exist, but also the mitigation measures (in your own study and for future research).

#11: How can your findings be put into practice?

Another classic question in the typical viva voce.

With this question, your committee is assessing your ability to bring your findings back down to earth and demonstrate their practical value and application. Importantly, this question is not about the contribution to academia or the overall field of research (we’ll get to that next) – it is specifically asking about how this newly created knowledge can be used in the real world.

Naturally, the actionability of your findings will vary depending on the nature of your research topic. Some studies will produce many action points and some won’t. If you’re researching marketing strategies within an industry, for example, you should be able to make some very specific recommendations for marketing practitioners in that industry.

To help you flesh out points for this question, look back at your original justification for the research (i.e. in your introduction and literature review chapters). What were the driving forces that led you to research your specific topic? That justification should help you identify ways in which your findings can be put into practice.

#12: How has your research contributed to current thinking in the field?

While the previous question was aimed at practical contribution, this question is aimed at theoretical contribution . In other words, what is the significance of your study within the current body of research? How does it fit into the existing research and what does it add to it?

This question is often asked by a field specialist and is used to assess whether you’re able to place your findings into the research field to critically convey what your research contributed. This argument needs to be well justified – in other words, you can’t just discuss what your research contributed, you need to also back each proposition up with a strong why .

To answer this question well, you need to humbly consider the quality and impact of your work and to be realistic in your response. You don’t want to come across as arrogant (“my work is groundbreaking”), nor do you want to undersell the impact of your work. So, it’s important to strike the right balance between realistic and pessimistic .

This question also opens the door to questions about potential future research . So, think about what future research opportunities your study has created and which of these you feel are of the highest priority.

Discuss your contribution in your thesis defence

#13: If you could redo your research, how would you alter your approach?

This question is often used to wrap up a viva voce as it brings the discussion full circle.

Here, your committee is again assessing your ability to clearly identify and articulate the limitations and shortcomings of your research, both in terms of research design and topic focus . Perhaps, in hindsight, it would have been better to use a different analysis method or data set. Perhaps the research questions should have leaned in a slightly different direction. And so on.

This question intends to assess whether you’re able to look at your work critically , assess where the weaknesses are and make recommendations for the future. This question often sets apart those who did the research purely because it was required, from those that genuinely engaged with their research. So, don’t hold back here – reflect on your entire research journey ask yourself how you’d do things differently if you were starting with a  blank canvas today.

Recap: The 13 Key Dissertation Defense Questions

To recap, here are the 13 questions you need to be ready for to ace your dissertation or thesis oral defense:

As I mentioned, this list of dissertation defense questions is certainly not exhaustive – don’t assume that we’ve covered every possible question here. However, these questions are quite likely to come up in some shape or form in a typical dissertation or thesis defense, whether it’s for a Master’s degree, PhD or any other research degree. So, you should take the time to make sure you can answer them well.

Defending Your Dissertation: A Guide

A woman in front of a bookshelf speaking to a laptop

Written by Luke Wink-Moran | Photo by insta_photos

Dissertation defenses are daunting, and no wonder; it’s not a “dissertation discussion,” or a “dissertation dialogue.” The name alone implies that the dissertation you’ve spent the last x number of years working on is subject to attack. And if you don’t feel trepidation for semantic reasons, you might be nervous because you don’t know what to expect. Our imaginations are great at making The Unknown scarier than reality. The good news is that you’ll find in this newsletter article experts who can shed light on what dissertations defenses are really like, and what you can do to prepare for them.

The first thing you should know is that your defense has already begun. It started the minute you began working on your dissertation— maybe even in some of the classes you took beforehand that helped you formulate your ideas. This, according to Dr. Celeste Atkins, is why it’s so important to identify a good mentor early in graduate school.

“To me,” noted Dr. Atkins, who wrote her dissertation on how sociology faculty from traditionally marginalized backgrounds teach about privilege and inequality, “the most important part of the doctoral journey was finding an advisor who understood and supported what I wanted from my education and who was willing to challenge me and push me, while not delaying me.  I would encourage future PhDs to really take the time to get to know the faculty before choosing an advisor and to make sure that the members of their committee work well together.”

Your advisor will be the one who helps you refine arguments and strengthen your work so that by the time it reaches your dissertation committee, it’s ready. Next comes the writing process, which many students have said was the hardest part of their PhD. I’ve included this section on the writing process because this is where you’ll create all the material you’ll present during your defense, so it’s important to navigate it successfully. The writing process is intellectually grueling, it eats time and energy, and it’s where many students find themselves paddling frantically to avoid languishing in the “All-But-Dissertation” doldrums. The writing process is also likely to encroach on other parts of your life. For instance, Dr. Cynthia Trejo wrote her dissertation on college preparation for Latin American students while caring for a twelve-year-old, two adult children, and her aging parents—in the middle of a pandemic. When I asked Dr. Trejo how she did this, she replied:

“I don’t take the privilege of education for granted. My son knew I got up at 4:00 a.m. every morning, even on weekends, even on holidays; and it’s a blessing that he’s seen that work ethic and that dedication and the end result.”

Importantly, Dr. Trejo also exercised regularly and joined several online writing groups at UArizona. She mobilized her support network— her partner, parents, and even friends from high school to help care for her son.

The challenges you face during the writing process can vary by discipline. Jessika Iwanski is an MD/PhD student who in 2022 defended her dissertation on genetic mutations in sarcomeric proteins that lead to severe, neonatal dilated cardiomyopathy. She described her writing experience as “an intricate process of balancing many things at once with a deadline (defense day) that seems to be creeping up faster and faster— finishing up experiments, drafting the dissertation, preparing your presentation, filling out all the necessary documents for your defense and also, for MD/PhD students, beginning to reintegrate into the clinical world (reviewing your clinical knowledge and skill sets)!”

But no matter what your unique challenges are, writing a dissertation can take a toll on your mental health. Almost every student I spoke with said they saw a therapist and found their sessions enormously helpful. They also looked to the people in their lives for support. Dr. Betsy Labiner, who wrote her dissertation on Interiority, Truth, and Violence in Early Modern Drama, recommended, “Keep your loved ones close! This is so hard – the dissertation lends itself to isolation, especially in the final stages. Plus, a huge number of your family and friends simply won’t understand what you’re going through. But they love you and want to help and are great for getting you out of your head and into a space where you can enjoy life even when you feel like your dissertation is a flaming heap of trash.”

While you might sometimes feel like your dissertation is a flaming heap of trash, remember: a) no it’s not, you brilliant scholar, and b) the best dissertations aren’t necessarily perfect dissertations. According to Dr. Trejo, “The best dissertation is a done dissertation.” So don’t get hung up on perfecting every detail of your work. Think of your dissertation as a long-form assignment that you need to finish in order to move onto the next stage of your career. Many students continue revising after graduation and submit their work for publication or other professional objectives.

When you do finish writing your dissertation, it’s time to schedule your defense and invite friends and family to the part of the exam that’s open to the public. When that moment comes, how do you prepare to present your work and field questions about it?

“I reread my dissertation in full in one sitting,” said Dr. Labiner. “During all my time writing it, I’d never read more than one complete chapter at a time! It was a huge confidence boost to read my work in full and realize that I had produced a compelling, engaging, original argument.”

There are many other ways to prepare: create presentation slides and practice presenting them to friends or alone; think of questions you might be asked and answer them; think about what you want to wear or where you might want to sit (if you’re presenting on Zoom) that might give you a confidence boost. Iwanksi practiced presenting with her mentor and reviewed current papers to anticipate what questions her committee might ask.  If you want to really get in the zone, you can emulate Dr. Labiner and do a full dress rehearsal on Zoom the day before your defense.

But no matter what you do, you’ll still be nervous:

“I had a sense of the logistics, the timing, and so on, but I didn’t really have clear expectations outside of the structure. It was a sort of nebulous three hours in which I expected to be nauseatingly terrified,” recalled Dr. Labiner.

“I expected it to be terrifying, with lots of difficult questions and constructive criticism/comments given,” agreed Iwanski.

“I expected it to be very scary,” said Dr. Trejo.

“I expected it to be like I was on trial, and I’d have to defend myself and prove I deserved a PhD,” said Dr Atkins.

And, eventually, inexorably, it will be time to present.  

“It was actually very enjoyable” said Iwanski. “It was more of a celebration of years of work put into this project—not only by me but by my mentor, colleagues, lab members and collaborators! I felt very supported by all my committee members and, rather than it being a rapid fire of questions, it was more of a scientific discussion amongst colleagues who are passionate about heart disease and muscle biology.”

“I was anxious right when I logged on to the Zoom call for it,” said Dr. Labiner, “but I was blown away by the number of family and friends that showed up to support me. I had invited a lot of people who I didn’t at all think would come, but every single person I invited was there! Having about 40 guests – many of them joining from different states and several from different countries! – made me feel so loved and celebrated that my nerves were steadied very quickly. It also helped me go into ‘teaching mode’ about my work, so it felt like getting to lead a seminar on my most favorite literature.”

“In reality, my dissertation defense was similar to presenting at an academic conference,” said Dr. Atkins. “I went over my research in a practiced and organized way, and I fielded questions from the audience.

“It was a celebration and an important benchmark for me,” said Dr. Trejo. “It was a pretty happy day. Like the punctuation at the end of your sentence: this sentence is done; this journey is done. You can start the next sentence.”

A thesis is a large paper, or multi-chapter work, based on a topic relating to your field of study.

Once you hand in your thesis, you will be assigned a date to defend your work. Your thesis defense meeting usually consists of you and a committee of two or more professors working in your program. It may also include other people, like professionals from other colleges or those who are working in your field.

During your thesis defense, you will be asked questions about your work. The main purpose of your thesis defense is for the committee to make sure that you actually understand your field and focus area.

The questions are usually open-ended and require the student to think critically about their work. By the time of your thesis defense, your paper has already been evaluated. The questions asked are not designed so that you actually have to aggressively "defend" your work; often, your thesis defense is more of a formality required so that you can get your degree.

  • Check with your department about requirements and timing.
  • Re-read your thesis.
  • Anticipate questions and prepare for them.
  • Create a back-up plan to deal with technology hiccups.
  • Plan de-stressing activities both before, and after, your defense.

How long your oral thesis defense is depends largely on the institution and requirements of your degree. It is best to consult your department or institution about this. In general, a thesis defense may take only 20 minutes, but it may also take two hours or more. The length also depends on how much time is allocated to the presentation and questioning part.

Tip: Check with your department or institution as soon as possible to determine the approved length for a thesis defense.

First of all, be aware that a thesis defense varies from country to country. This is just a general overview, but a thesis defense can take many different formats. Some are closed, others are public defenses. Some take place with two committee members, some with more examiners.

The same goes for the length of your thesis defense, as mentioned above. The most important first step for you is to clarify with your department what the structure of your thesis defense will look like. In general, your thesis defense will include:

  • your presentation of around 20-30 minutes
  • questions from the committee
  • questions from the audience (if the defense is public and the department allows it)

You might have to give a presentation, often with Powerpoint, Google slides, or Keynote slides. Make sure to prepare an appropriate amount of slides. A general rule is to use about 10 slides for a 20-minute presentation.

But that also depends on your specific topic and the way you present. The good news is that there will be plenty of time ahead of your thesis defense to prepare your slides and practice your presentation alone and in front of friends or family.

Tip: Practice delivering your thesis presentation in front of family, friends, or colleagues.

You can prepare your slides by using information from your thesis' first chapter (the overview of your thesis) as a framework or outline. Substantive information in your thesis should correspond with your slides.

Make sure your slides are of good quality— both in terms of the integrity of the information and the appearance. If you need more help with how to prepare your presentation slides, both the ASQ Higher Education Brief and James Hayton have good guidelines on the topic.

The committee will ask questions about your work after you finish your presentation. The questions will most likely be about the core content of your thesis, such as what you learned from the study you conducted. They may also ask you to summarize certain findings and to discuss how your work will contribute to the existing body of knowledge.

Tip: Read your entire thesis in preparation of the questions, so you have a refreshed perspective on your work.

While you are preparing, you can create a list of possible questions and try to answer them. You can foresee many of the questions you will get by simply spending some time rereading your thesis.

Here are a few tips on how to prepare for your thesis defense:

You can absolutely prepare for most of the questions you will be asked. Read through your thesis and while you're reading it, create a list of possible questions. In addition, since you will know who will be on the committee, look at the academic expertise of the committee members. In what areas would they most likely be focused?

If possible, sit at other thesis defenses with these committee members to get a feel for how they ask and what they ask. As a graduate student, you should generally be adept at anticipating test questions, so use this advantage to gather as much information as possible before your thesis defense meeting.

Your thesis defense is a formal event, often the entire department or university is invited to participate. It signals a critical rite of passage for graduate students and faculty who have supported them throughout a long and challenging process.

While most universities don't have specific rules on how to dress for that event, do regard it with dignity and respect. This one might be a no-brainer, but know that you should dress as if you were on a job interview or delivering a paper at a conference.

It might help you deal with your stress before your thesis defense to entrust someone with the smaller but important responsibilities of your defense well ahead of schedule. This trusted person could be responsible for:

  • preparing the room of the day of defense
  • setting up equipment for the presentation
  • preparing and distributing handouts

Technology is unpredictable. Life is too. There are no guarantees that your Powerpoint presentation will work at all or look the way it is supposed to on the big screen. We've all been there. Make sure to have a plan B for these situations. Handouts can help when technology fails, and an additional clean shirt can save the day if you have a spill.

One of the scariest aspects of the defense is the possibility of being asked a question you can't answer. While you can prepare for some questions, you can never know exactly what the committee will ask.

There will always be gaps in your knowledge. But your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. You are not expected to know everything.

James Hayton writes on his blog that examiners will sometimes even ask questions they don't know the answer to, out of curiosity, or because they want to see how you think. While it is ok sometimes to just say "I don't know", he advises to try something like "I don't know, but I would think [...] because of x and y, but you would need to do [...] in order to find out.” This shows that you have the ability to think as an academic.

You will be nervous. But your examiners will expect you to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions, for example. Dora Farkas at finishyourthesis.com notes that it’s a myth that thesis committees are out to get you.

Two common symptoms of being nervous are talking really fast and nervous laughs. Try to slow yourself down and take a deep breath. Remember what feels like hours to you are just a few seconds in real life.

  • Try meditational breathing right before your defense.
  • Get plenty of exercise and sleep in the weeks prior to your defense.
  • Have your clothes or other items you need ready to go the night before.
  • During your defense, allow yourself to process each question before answering.
  • Go to dinner with friends and family, or to a fun activity like mini-golf, after your defense.

Allow yourself to process each question, respond to it, and stop talking once you have responded. While a smile can often help dissolve a difficult situation, remember that nervous laughs can be irritating for your audience.

We all make mistakes and your thesis defense will not be perfect. However, careful preparation, mindfulness, and confidence can help you feel less stressful both before, and during, your defense.

Finally, consider planning something fun that you can look forward to after your defense.

It is completely normal to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions for example if needed. Slow yourself down, and take a deep breath.

Your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. James Hayton writes on his blog that it is ok sometimes to just say "I don't know", but he advises to try something like "I don't know, but I would think [...] because of x and y, you would need to do [...] in order to find out".

Your Powerpoint presentation can get stuck or not look the way it is supposed to do on the big screen. It can happen and your supervisors know it. In general, handouts can always save the day when technology fails.

  • Dress for success.
  • Ask for help setting up.
  • Have a backup plan (in case technology fails you).
  • Deal with your nerves.

Preparing for your dissertation defense, published by steve tippins on april 4, 2019 april 4, 2019.

Last Updated on: 30th August 2022, 04:43 am

Preparing for your dissertation defense is one of the most important things you’ll do as a doctoral candidate. Now that you’ve completed your dissertation, it’s up to you to present the results to your committee.

However, the results aren’t just about your study. Your committee wants to see what you learned through the process and whether you are ready to take on the responsibility of being a scholar.

What is a Dissertation Defense?

When you finish your dissertation and your committee has said you are ready to move forward, there is a formal meeting–your dissertation defense–where you have the opportunity to explain what you did and what you found.

Your committee then has the opportunity to ask questions related to your work, the implications of what you found, and your future. It is a chance for you to stand before your peers and be welcomed into the academy. Defending your dissertation is one of the great rites of passage into the world of academia.

How to Prepare for Your Dissertation Defense

Rather than write a quick list of dissertation defense tips, I thought I’d create a comprehensive guide to defending your dissertation. After chairing and sitting on countless dissertation committees, these are the steps I recommend you take.

Cultivate The Right Attitude

Perhaps the most important thing to have as you prepare to defend your dissertation is a revised view of your academic self. You’ve spent years gaining knowledge on your chosen subject, and now is your time to shine. While it’s natural to be nervous — after all, you’re jumping the highest hurdle in academia — keep in mind that this is your moment to shine and that you are now an expert on the topic.

One way to look at the dissertation defense is as a rite of passage. You are being tested, and just as with any rite of passage, the more rigorous the test, the prouder you will be of making it through.

During the process of your defense, keep this in mind: your committee tests you not only to ensure your worthiness but also to enable you to see just how much you know; to step into your new role as “expert.”

Prepare For Your Committee’s Questions

With this attitude in mind, you will want to prepare to demonstrate your expertise. That means anticipating questions the committee may have about your research.

If your dissertation asserts the likelihood of a recession in the presence of particular economic indicators, your committee will want to know what socio-political conditions are linked to these indicators. If you found that high achieving students are more likely to have had parents who volunteered in their schools, your committee members will likely ask you to speculate about how to increase parent involvement in schools.

In other words, you’ll need to be able to participate in discourse beyond your results — questions that speak to the relevance and implications of your research.

This kind of preparation goes beyond creating a PowerPoint of your findings (though that is necessary too); it’s part of your stepping into your expert role.

One thing I always tell my students is “Be able to explain your topic to your grandparents,” because to elucidate someone who knows nothing about the topic (no offense to the grandparents!) you must know it inside and out.

Of course, you’ll also want to know your topic well enough to discuss the topic with the top researchers in the field, but at this stage, you’ll have read enough of their work that you’ll feel you know them personally. It’s usually more difficult for academics to simplify than to complicate.

To ready yourself for potential questions, give your abstract to a few friends outside your academic program and have them ask you questions about your study. The advantage is their “outsider” perspective; you’ll have fun answering their questions and will likely have to make a few new neuronal connections to do so. Practicing like this will also help you relax during the actual defense.

Here are some questions you may be asked during your dissertation defense :

  • “What are the strengths and weaknesses of your study?”
  • “What was the most surprising thing you found?”
  • “What will you do next with your results?”
  • “If you could do this over, what would you do differently?”

Organize Your Presentation

Keep in mind that your presentation to your committee can double as your presentation to the faculty at any university to which you apply; your preparation will serve a dual purpose. You’ll need, therefore:

  • a concise overview of the literature in which your study is grounded,
  • a clear description of your study’s purpose, methodology, and findings,
  • and a discussion of the implications of these findings.

Naturally, you will need to consult your department’s and college’s specific requirements, but every dissertation committee (and faculty search committee) will want to fully understand these basic elements of your work.

I have provided a list of questions to help prepare your dissertation defense. If you have time restrictions I would put more emphasis upon your results and the implications of your work. Think of organizing your slides according to these questions:

1. Why did I choose to study this? Don’t be afraid to reveal something personal about your motivation, as long as you can do so with poise and dignity. Your committee members will appreciate this humanizing element but keep it brief!

2. What have other people interested in this topic found? If your study is the next clue in the hunt for answers about this topic, what were the clues that led you here? What paths have past researchers gone down — both fruitful and not? What solid theoretical foundation stands under your study?

This portion of your presentation is the easiest to overdo. You will likely need to edit it again and again to ensure it is both concise and comprehensive. Stick to the major themes in your presentation but be prepared to answer questions about less dominant streams of research.

3. How did my research question evolve? Answering this question links your research to what has already been established, placing your study in the stream of knowledge. Keep it brief but don’t skip this step, as it is key to showing you as an academic, rather than a student.

4. How did I organize my study? This is a description of the basics of your study and the “whys” of these choices. You can expand a bit here, as the decisions you made at this stage demonstrate your ability to think critically about approaching a research question. Why did you choose your particular methodology? What was the benefit of this design over another option you might have chosen?

5. What did I find? You can begin this section with what you expected to find and why, then explain what you actually found. Keep this section simple and factual.

6. What do the findings mean in relation to the question? Whether or not your findings matched your expectations, they tell you and your colleagues something important about the topic. What is it? Can we speculate that this is a promising area of research, or is this a path we might think of as a dead end? What, exactly, does this study tell us?

7. What’s next for me and for the research? You’ll want to give your committee (and any faculty search committee) a preview of your prospective academic career. What new questions has your study sparked for you? What would you hope other researchers would look at next? How do you intend to fit into the academic conversation on this topic?

Depending on your committee and requirements, you may want to include potential grants you will consider applying for to fund your next study. (This inclusion becomes more important when applying for academic positions.)

Prepare Yourself Mentally

Going back to attitude, remind yourself that a dissertation defense is your opportunity to step into your new role. This is your domain now. Breathe deeply and feel the pride that comes with a job well done. Know that you belong in this realm and the dissertation defense is your chance to prove it. Be humble, too; after all, you stand on the shoulders of giants.

Getting enough rest the night before, drinking water and bringing some with you to drink when your mouth gets dry, and being wise about what you consume prior to the defense (maybe go easy on the carbs and caffeine) are all obvious but frequently overlooked pointers. Your committee members want to know you can handle the pressure and take care of yourself under duress .

You might want to give yourself a few minutes of silence and rest before heading in to defend. Take those moments to recognize whatever you’re feeling, then humbly begin your academic career by presenting your most important work to date. And then get ready to roll up your sleeves for the next one. Congratulations, Doctor!

How to Prepare for Your Dissertation Defense

How to Prepare for Your Dissertation Defense

4-minute read

  • 1st August 2023

After years of research and study, you’ve finally reached the grand finale of your PhD years: your dissertation defense. Since defending your dissertation is the culmination of all your hard work, it’s essential to do everything you can to prepare for it.

In this post, we’ll take you through how to ready yourself for your dissertation defense so you can focus on your accomplishments and excel during this crucial professional moment.

What is a Dissertation Defense? 

The dissertation defense is the crowning moment of years of research – the final examination before a PhD student is awarded their doctoral degree.

During a dissertation defense, the student presents their research, methodology, findings, and conclusions to a committee of faculty members and experts in their field. The committee then engages in a question-and-answer session to assess the student’s understanding of the subject matter, the quality of their research, and their ability to defend their work under scrutiny.

Many PhD students consider it to be the defining moment of their academic career and their chance to prove their expertise in their chosen research field.

If all this sounds overwhelming – don’t worry. If you’re a PhD student, you’ll have plenty of time and opportunity to adequately prepare for your dissertation defense. Below are some strategies to help you get ready for this significant occasion in your career.

1.   Know the Requirements

Familiarize yourself with your institution’s guidelines and requirements for the defense process. Understanding the format, time limit, and expectations for the presentation will help you to prepare your material and anticipate any issues.

2.   Review Your Dissertation

Even if you think you know it inside and out, review your dissertation from beginning to end. It may have been some time since you’ve last read and considered certain portions of your research and findings. Consider what your committee might ask about your research questions , data analysis, and conclusions.

3.   Work on Starting Strong

To begin your defense on a strong note, work on creating a clear and engaging introduction. You can start by briefly outlining the purpose of your study, research questions, and methodology . Try to stay on topic and don’t veer off track by discussing unrelated or unnecessary information.

4.   Practice Presenting

Practice your presentation skills by rehearsing your defense multiple times. Focus on clarity and pacing and try to stay within the allotted time limit. It also helps to record yourself so that you can see yourself from your audience’s point of view.

5.   Practice Q&A Sessions

To build your confidence, enlist friends and colleagues to conduct mock question-and-answer sessions. When practicing, remember to pause before answering questions you’re unsure of. It’s better to take your time delivering a response than it is to give an inaccurate or incorrect answer.

6.   Seek Feedback

Find out if your institution offers mock defense sessions where peers or mentors play the role of the committee, ask you questions, and give feedback . You can also have colleagues, mentors, or advisors review your presentation and offer practical feedback.

7.   Create Visual Aids

Think about any visual aids , such as slides, you may want to use to illustrate your defense and prepare them in advance. Be sure to check that your university allows visuals or images and that they enhance, rather than overwhelm, your presentation.

8.   Stay Calm and Confident

It’s natural to feel nervous but try to stay calm and composed during your defense. Take deep breaths and remind yourself of the expertise you’ve gained through the experience of writing your dissertation.

Dissertation Defense: Steps To Follow To Succeed

dissertation defense

A dissertation defense is arguably one of the most important milestones in every student’s career. While it signals that your tenure as a student is soon about to close, it validates all your efforts towards your thesis.

Being cautious about including all the necessary details is very important to successfully complete your dissertation proposal defense. This article tells you everything that you need to know about writing a defense that can add great credibility to you as a student.

What is A Dissertation Defense?

The first thing that you need to learn is what is a dissertation defense and what is its purpose. In simple terms, it is a presentation made by a student to defend all the ideas and views that are presented in a dissertation.

The presenter must include details like what is the reason for choosing specific research methods, the theory that has been selected for the paper, and other such points. This presentation is made before an audience that comprises of the university committee, professors and even fellow-students. It is met with questions and answers that gives the student an opportunity to provide more clarity on the dissertation in order to convince the committee to approve it.

Stages of a Dissertation Defense

One of the most important dissertation defense tips provided by several professors is to breakdown the process into three steps:

  • Preparation : This stage involves collection of all the necessary information that must be included in the defense dissertation and making all the arrangements for the actual meeting.
  • The defense meeting : This is where you decide how you will present the defense. The actual meeting is hugely reliant on the performance, body language and the confidence in your oral defense.
  • After the defense meeting : This stage, also known as the follow up, requires you to make the necessary revisions suggested by the university committee. You can even provide bound copies of the whole dissertation to distribute among different members of your departments. In the follow up stage, one must also think about expense that are related to publishing the Ph.D. dissertation defense as well as printing additional copies of the manuscript, if required.

How Long is a Dissertation Defense?

The first thing that a student should know is how long does a dissertation defense last? The length has to be carefully calculated to make the impact that you want. One of the most important steps in the dissertation preparation is to understand how much time each department allocates to the closing oral defense. When you plan in the early stages of your dissertation itself, you can write it in a manner that allows you to defend it in the allocated time.

Usually these meetings including the presentation, the oral defense and the question and answer session last for about two hours. In most cases, these two hours also encompass the time needed by members of the committee to deliberate.

How to Prepare for the Dissertation Defense

Now that you know how long is a dissertation defense, the next step is to prepare well enough to make your presentation impressive.

Here are some tips on how to prepare for a dissertation defense:

  • Watch other students in action to learn about different presentation styles. You can attend defenses of different colleagues in your department as well as other departments in your university.
  • Get all the details about the deadlines and the rules of your college or university about scheduling your defense.
  • Scheduling is also a very important part of your preparation. It is important to note that members of the committee and University chairs need to make time for these defences in a very packed schedule. Coordinate the date, venue and time of your defense as early as possible.
  • Prepare a manuscript adhering to the necessary formatting rules. Review your manuscript thoroughly before you hand it in. During your PH.D, your faculty will also assist you with the defense. For this, they must have a crisp and polished copy of your manuscript.
  • Most colleges have the facility for a pre-defense meeting. This is the best opportunity to sort out any concerns that you may have about the actual meeting. It is a good idea to ask the chairs what types of questions may be put forward and if there are any problems with the defense that need to be resolved. When you prepare for a pre-defense meeting, think of it as the final one and give it your all.
  • Put together all the material that you need for the defense. A detailed, yet to-the-point presentation must be prepared.
  • The final stage of preparation is practicing your presentation over and over again. It is not just the presentation but also the approach towards the questions that you must practice.

Tips To Nail Your Actual Meeting

With these tips you will be one step closer towards a successful defense that will help your dissertation pass and be approved:

  • All meetings should begin by addressing the chair. Make sure you thank all the committee members and the advisors for the efforts that they have put it. This gives you a professional start to the presentation.
  • The presentation should cover the following subjects in brief:
  • The research topic
  • Literature review
  • The methods used for analysis
  • The primary findings of the research
  • Recommendations of additional research on the subject in the focus.
  • Do not get rattled by any discussions among the chairs. They will deliberate on any disagreements or topics of interest. This is a part of the process and is not a reflection of the presentation itself.
  • There are two questions that are commonly asked that you should be prepared for. This includes the weaknesses of the dissertation and the research plans that you have made post-dissertation.
  • Use subtle gestures when you are talking. Do not overuse your hands when doing so. The whole meeting including the question and answer session should have a very formal appeal.
  • The tone of your voice must be assertive without making it seem like you are trying to hard. Be clear and enunciate when you speak.

Once the questions have been answered, the committee will leave the room. Then, after the deliberation, you will be informed if your dissertation has passed or not.

13 Tips to Succeed in Your PhD Dissertation Defense

Thesis definition.

A research thesis is presented by one or more postgraduate students to receive a degree in their field of study.

dissertation defense advice

Medical editing, Medical Publishing

The thesis represents all the stages of a study from the subject selection time to the conclusion. A thesis must have a new subject.

Dissertation definition

The research project at the end of a postgraduate is called a dissertation.

In the selection of a dissertation subject, it is necessary to investigate a new subject

What is the difference between a thesis and a dissertation?

  • A Ph.D. dissertation is more comprehensive than a master’s thesis.
  • A thesis can complete previous studies but a dissertation must necessarily be the result of a study on a new subject.
  • A Ph.D. dissertation requires further explanations to provide a new idea that leads to a new advancement.
  • A Ph.D. proposal is more detailed because it provides a complete explanation of what is discussed in the thesis.
  • The purpose of writing a master’s thesis is to become familiar with the research process; however, in a postgraduate program, students should have sufficient ability in conducting research and writing a dissertation, so that they can independently carry out a research project.
  • Ph.D. dissertations include broader ranges, stronger assumptions, more intelligent analyses, and more innovations.
  • In dissertations, the researcher should be able to present a new advancement or state a theory that rejects or confirms the previous ideas.

How well do you know your project? Are you ready for your Ph.D. dissertation defense? For several years, you have conducted experiments, analyzed the results of these experiments, and conducted thousands of studies on your thesis to reach this level of knowledge about your research thesis. Defending your Ph.D. dissertation is the last step of your doctoral studies. Researchers often wonder how they can excel at their thesis defense, and therefore, spend countless hours trying to create this edge over their peers. It takes days, weeks, months, and possibly years of effort to complete your doctorate and surpass the dissertation defense hurdle.

In this DoNotEdit article, we point out the details of how to excel at a Ph.D. dissertation defense and list down some interesting tips to prepare for and succeed in your thesis defense meeting.

dissertation defense advice

1. Start Preparation for Your Ph.D. Dissertation Defense Early

The thesis defense is not a 3- or 6-month exercise. Don’t wait until you’ve completed all of your research objectives. Start preparation for your thesis defense as early as possible and make sure you understand all the intricacies of your thesis and the reasons for all the research experiments you have conducted.

2. Attend Other Researchers’ Presentations

Participate in open dissertation presentations at your university. You can also attend open dissertation presentations at other universities too. First, it will help you realize that defending your thesis is not a scary process. Second, you will learn tips and tricks from other researchers on how to defend your thesis. Finally, you will understand why the thesis defense is necessary for the university as well as the scientific community.

3. Spend Enough Time to Prepare the Slides

The dissertation defense process is more difficult than submitting the thesis before the deadline. Ideally, you can start preparing the slides after you have finalized your thesis. Spend more time preparing the slides. Make sure you include the right data on the slides and restate your conclusions to create a logical flow for your presentation.

4. Spend Enough Time Designing the Structure of the Presentation

Take enough time to create a structured presentation. Additionally, create high-quality slides that will impress committee members. Create slides that grab your audience’s attention. Design the presentation completely and accurately and use smart software to create better slides.

5. Practice Breathing Techniques

If you watch a few TED-talk videos, you will notice that the speakers are very fluent in their speech. In fact, you won’t notice their breathing or shortness of breath. The only reason behind the speaking skills of these speakers is the practice of breathing techniques.

In addition, every speaker knows how to control his breath. Long and steady breaths are very important. Pay attention to your breathing and slow it down. All you need before this moment is a little practice.

6. Create an Impressive Introduction

The audience expects a lot from you to draw their attention to your thesis topic, so your opening statement should captivate the audience. Additionally, your thesis must impress the members of the thesis committee. They should be excited about your thesis and how you present your information about it.

The introduction answers the most important questions, most importantly “Is this presentation worth my time?” Therefore, it is important to make a good first impression, as the tone of your presentation in the first few minutes will set the tone for the audience throughout the presentation.

7. Make a List of Questions about Your Thesis

While preparing for the presentation, write down all the questions that you can ask yourself about your doctoral thesis. Try to write down all the questions from the thesis reader’s point of view on a sheet and answer them. Pretend you don’t know the topic of the thesis and think of questions that can help you understand the topic better.

The list of questions will prepare you for the questions the members may pose while trying to understand your research. Attending other candidates’ open discussions will also help you assume the dissertation defense questions.

8. Practice Speech and Body Language

After you have successfully prepared your slides and exercised, you can start focusing on how you look while presenting your thesis. This exercise is not for your appearance but to know your body language and practice being relaxed while presenting your thesis.

Pay attention to your body language. Stand up straight, but relax your shoulders. Correct posture helps to boost your self-confidence. So, look at yourself in the mirror and pay attention to the movements you make.

9. Fictitious Presentation

Recreate your thesis defense session as a test. Your mock defense will be very similar to your real defense and you will gain experience with real defense.

10. Learn How to Deal with Your Mistakes

Everyone makes mistakes. However, it’s important to keep going. Do not let your mistakes in the defense session affect the entire thesis defense session. Take a deep breath and continue to defend your thesis.

11. Control Your Nerves during Presentation

If you are nervous on the day of the defense, you may try to finish the presentation faster. Finishing the presentation faster will make you more anxious, and therefore, you may talk too fast and skip important details. Ultimately, being nervous on the defense day will result in failing your thesis defense.

12. Get Enough Rest

Among the tips for preparing for the defense of the thesis, sufficient disclosure is extremely important. Obviously, it’s hard to sleep the day before this big event, but you need to focus and go to bed early. You need to get the rest you deserve.

13. Visualize Yourself Defending Your Thesis

This simple exercise has a big impact on your self-confidence. All you have to do is to visualize yourself giving a successful speech. Every day, until the day of the defense of the thesis, imagine yourself in front of the audience as you are giving a speech and going from one point to another. This exercise takes a lot of commitment and persistence, but the results, in the end, pay off. Visualization makes you see yourself doing the scary thing of defending your thesis.

If you have all these tips in mind, you are ready for your big day. You have worked tirelessly for your Ph.D. and you will definitely do your best to succeed in defending your PhD thesis.

What is a dissertation defense?

The final oral examination for a doctoral candidate, commonly known as the dissertation defense, represents the conclusive formal stage prior to the submission of the dissertation manuscript and the conferral of the doctoral degree. This examination centers on the dissertation itself and its relevance within the candidate's area of academic specialization.

A successful defense is the peak of your academic career, so don’t treat it lightly. Make sure that you take enough time to learn everything there is to know about the topic and prepare well. If you look at your paper and it seems raw or unfinished, and especially if your academic advisor says so, it might be best to take another semester for prep. We don’t mean to scare you, but it truly is a responsible moment, and if you fail your defense, all the years of hard work will be wasted.

Defending doctoral dissertation is not going to be easy. If you don’t get to choose the members of your board and you will be met with unfamiliar faces, you might start to panic and feel lost. This is exactly why you need to be over-prepared. In fact, there’s no such thing as being overly prepared when it comes to your defense. Think of all the possible questions your dissertation committee members may have, even the most far-fetched ones, and then find the answers.

Doctoral dissertation defense process

During the dissertation defense, the candidate delivers an oral presentation of their dissertation to the Supervisory Committee (refer to the Supervisory Committee Policy) and to a public audience. The length of both the oral presentation and the subsequent question-and-answer session is determined through consultation between the Committee and the candidate, ensuring it meets the specific requirements and standards of the process.

The dissertation defense process, often the culmination of a doctoral program, is a critical step in the journey towards earning a PhD or similar advanced degree. This process involves several key stages designed to assess the quality, originality, and contribution of the candidate's research. Here's a general overview:

  • Completion of the Dissertation : Before the defense can be scheduled, the dissertation must be completed. This involves conducting original research, writing up the findings, and often, revising the document based on the advisor's feedback.
  • Submission of the Dissertation : Once the dissertation is completed and approved by the advisor, it must be submitted to the department or dissertation committee for review. This submission typically includes a written document detailing the candidate's research findings and conclusions.
  • Scheduling the Defense : After the dissertation is submitted, a defense date is scheduled. The timing of this can vary widely depending on the institution and the specific requirements of the department.
  • Preparation for the Defense : The candidate prepares a formal presentation of their research findings. This presentation is typically structured to highlight the research question, methodology, key findings, and the significance of the work.
  • The Defense Event : The defense itself is a public forum in which the candidate presents their research to the dissertation committee and often, an audience of peers, faculty, and sometimes the general public. Following the presentation, committee members and sometimes audience members ask questions related to the research and the findings.
  • Question and Answer Session : This session allows the committee to probe the candidate's understanding of the research area, methodology, and conclusions. The candidate must defend their research choices and conclusions, demonstrating deep knowledge of the subject.
  • Committee Deliberation : Following the Q&A, the committee deliberates in private to decide whether the candidate has successfully defended the dissertation. Criteria for success can include the originality of the research, the soundness of the methodology, and the significance of the contributions to the field.
  • Outcome Announcement : The committee then informs the candidate of the outcome. Possible outcomes can include pass, pass with minor revisions, pass with major revisions, or fail, although specifics can vary by institution.
  • Completion of Revisions (if required) : If the committee requires revisions, the candidate must complete these before the degree can be officially awarded. The scope of revisions can vary significantly.
  • Final Submission : After any required revisions are made and approved by the committee, the final version of the dissertation is submitted to the university. This often includes submitting bound copies of the dissertation and making it available through the university's library or institutional repository.
  • Graduation and Degree Conferral : Following successful defense and submission of the final dissertation, the candidate is eligible to graduate and receive their doctoral degree.

This process is a significant milestone in an academic career, representing the transition from student to scholar and contributing new knowledge to the field.

Even though it may seem horrible and nerve-racking, the process of defending your dissertation is pretty straightforward. And if you take your time to prepare for it well, you will not have any problems with the defense itself.

The scariest part is presenting your work to a group of professionals. You have to show your proficiency in the field, ability to think critically and withstand criticism. Most colleges and universities will allow you to choose your own committee. So, try to take your pick as early as possible so you’re not left with people the rest of your group didn’t want. 

How to defend dissertation?

Navigating your dissertation defense involves thorough prep, including understanding your institution's format, mastering your material, anticipating committee questions, and perfecting your presentation. During the defense, remain poised, address inquiries with depth, and interact professionally. Post-defense, be ready for revisions. Ensure professional attire, early arrival, and confidence in your expertise. Embrace feedback as growth. Celebrate this significant academic milestone, as it's not only an examination but a showcase of your scholarly journey.

Defending your dissertation is a pivotal moment in your academic career. Here's a step-by-step guide to prepare for and successfully defend your dissertation:

Let’s assume that your dissertation paper is done and approved. The next step after choosing your committee would be preparation. In one of the committee meetings, you will discuss how much time you have for your defense and the Q&A session afterward. Normally, the whole defense lasts about an hour, but it can vary depending on the number of doctoral students defending on the same day. 

Preparing for your defense means getting thoroughly acquainted with your paper. It might seem like a ridiculous piece of advice if you’ve written it yourself, yet, with a paper of that size, it’s easy to get lost. If you’ve used a dissertation writing service , you need to take special care in learning the contents of your paper. 

Prepare a presentation that you will be showing to the committee. Make sure the slides are clear and easy to understand, with most information placed in the speaker notes. You don’t want to overload the slides with text. 

Analyze your dissertation and think of all the possible questions the defense board members may have afterward. It’s hard to anticipate what a professional may ask about your ‘rookie’ paper, so it might help to speak to your academic advisor before the PhD defense . They might shed some light on the inconsistencies and possible lack of analysis in some areas. 

How to prepare for defense day?

When the day of defending dissertation finally comes, no matter how prepared you are, it will still be stressful. So, it makes sense to come over-prepared. Learn your dissertation text by hard.

Find every grammatical mistake and fix it. Get acquainted with every letter and word and really make sure it’s perfect. If you are convinced your paper is perfect, it will be hard for the defense board to convince you otherwise. 

How do I know I’m ready for my PhD dissertation defense?

Your academic advisor is your best friend in this situation. They have lots of experience in the matter, and they will be the first person to tell you if your paper is defense-proof. If you see them doubting or if they are asking lots of questions, use those questions as learning points. 

Most likely, they criticize you not because they hate you. But because they want to show you your gaps in knowledge. This is a powerful tool to help you find blank spots and fill them

What should I bring to my PhD thesis defense?

  • Presentation Materials : This includes any slides or visual aids you'll use to support your talk. Ensure they are ready and compatible with the equipment available.
  • Laser Pointer : Useful for highlighting specific areas or data on your slides during the presentation.
  • Copy of Your Dissertation : Have at least one printed copy for your own reference. It's helpful for addressing specific questions or sections during the Q&A.
  • Pen or Pencil : For making quick notes or annotations based on feedback or questions you may receive.
  • Notepad : To jot down notes, questions, or reminders during the defense.
  • Bottle of Water : Keeping hydrated is important, especially since you'll be speaking for an extended period.
  • Backup of Your Presentation : Have a backup on a USB drive or accessible online in case of technical difficulties.
  • Any Necessary Forms : Sometimes, there are forms that committee members need to sign post-defense. Check with your department for any such requirements.
  • Questions for Your Committee : Have a list of questions or clarifications you might want to ask your committee after your defense.
  • A Watch or Timer : To keep track of your presentation time and ensure you cover all points within the allotted duration.

Depending on how long is a PhD defense, you will need a different supply. If you are planning to sit through your whole class’ defense, you will need lots of water, some snacks to eat during the breaks, and your presentation materials.

However, if you are allowed to only show up to your defense and not listen to the entire class defend their dissertations, the most important thing you need to have is your dissertation and presentation. And don’t forget to bring some water, it can help you calm down if you get stressed.

Why does the dissertation length vary?

Various elements, such as institutional standards, the research's complexity, the extent of analysis, and the presence of supplementary materials, can determine a dissertation's length.

The length of your defense may also depend on how long is a dissertation . If your dissertation is 70 pages, your defense will definitely run shorter than if it is 300 pages long. The length of your paper will also influence the length of your PowerPoint presentation and the number of questions you get.

But how do you defend a dissertation? Defense is just an academic word for presenting your findings. You do your research, you present it to the board, and they ask you questions. By answering these questions, you defend the legitimacy and academic value of your doctoral defense research.

The key here is preparedness. Being well-acquainted with the contents of your paper and being able to defend it is your key to success. If you’re not sure about some parts of your dissertation, consult your academic advisor. They will be willing to help and advise you on whether you should take another semester to prepare.

Of course, it’s a great thing that ‘ write my dissertation ’ services exist. You can address a service like Studyfy and rely on it completely in the dissertation writing process. If you do, you can order your dissertation chapter by chapter and bring each draft to the professor for their notes and critiques.

What else do I need to know?

The most important part is you need to be prepared to defend dissertation meaning, and you need to know your dissertation by heart and be ready to justify every word in it. Sure, it may sound terrifying but thinking that millions of people have done that before you might give you some ease. 

How long is a dissertation defense?

Normally, defending my dissertation shouldn’t take more than an hour and a half. It usually lasts anywhere between 30 minutes and 1,5 hours.

It depends on your academic level, the number of people defending, and your preparedness. If the committee members sense you’re ill-prepared, they will ask you more questions.

It’s not because they want to thank you, but actually because they want to give you more chances. Asking more questions is usually an attempt to find an area that you’re very good at to give you a chance to redeem yourself.Your doctoral defense ia an important part of your doctoral journey, and it's bound to be more intense than a bachelor’s one. That’s only natural. Since your doctoral dissertation will be more in-depth, show a deeper understanding of the subject and better proficiency. 

The length of your defense will depend on many factors. But the most important one is your preparedness and confidence. If you are not prepared well, the dissertation committee will ask you lots of questions. They do that to find an area of study that you are good at, but at that moment, it might make you even more stressed. So, coming prepared is the best thing you can do for your defense to be successful. 

Using services like Studyfy is also an option. Yet, you must understand that if you show up with a perfectly written paper, yet you have no idea what it’s about, it will raise even more questions. That’s why you must prepare very well, regardless if you write your paper yourself or outsource it. If you still have some questions about how to write a dissertation , make sure to read our guide.

What is the key to dissertation defense?

Comprehensive Preparation: Familiarize yourself with your institution's defense protocols and engage in extensive practice. Segment your thesis for easier presentation, manage timing, highlight essential arguments, and anticipate likely inquiries. Organize a practice defense session to gain comfort with the procedure.

The most important thing you need to do to defend my dissertation is to start your prep early enough. What does it mean to defend your dissertation? Your defense is the pinnacle of all the hard work you've put in your studies throughout the years. Every time you write a paper, you must understand that you may use that research for your dissertation. So, your prep for dissertation defense starts as soon as you enter college.

What is defending a dissertation? Are there dissertation committee members?

Defending dissertation meaning is the process of presenting your research and findings to the board. Regardless if you buy dissertation or write it yourself, you will need to defend it. This is why you need to prepare carefully for your defense - study your paper through and through, think about all the possible questions you may be asked and think of the answers.

The dissertation committee or the dissertation chair are faculty members that will simply ask dissertation defense questions - some about research methodology, and some about the primary role of your work. Before the actual oral defense, try setting up a mock defense with your friend and go over the important topics.

How long is a thesis defense?

It depends on the length of your paper. Since your master’s thesis will probably be a bit shorter than a doctorate dissertation, you can count on your oral defense lasting up to an hour. Again, the length of the doctorate defense depends on how well you are prepared and how you handle the professors’ questions.

How to Prepare for Your Dissertation Defense

December 14, 2021

dissertation defense advice

If you’re in a doctoral program, there’s no doubt you are dreaming of the day where you’ll be announced as “doctor” for the first time. However, it’s a long road to get there with many steps along the way, the biggest of which is the defense of your dissertation.

The dissertation defense is often shrouded in mystery. I equate it to the scene in “The Wizard of Oz” with the mysterious man behind the green curtain. But it doesn’t have to be. I’m pulling back the curtain with tips on how to prepare for your dissertation defense.

Attend a Defense

American College of Education allows you to attend the defenses of your colleagues remotely. This gives you the unique opportunity to see the defense process and understand what to expect. Take it one step further by attending a defense where your dissertation chair is involved so you get a sense of what they’re looking for in the process. I recommend reaching out to your chair ahead of time, as they can even help find a defense that’s a good fit for you to observe.

To find a list of upcoming defenses, go to the Dissertation Calendar in Student Commons. Remember, of course, to be a respectful audience member when attending a defense. While they are open to viewing, it’s still an intimate process solely belonging to the doctoral candidate.

Know the Rituals

The oral defense is similar to a wedding in that there is prescribed way in which events take place. Fortunately, ACE provides doctoral candidates with a detailed dissertation template that you’ll work through with your chair to fine tune your presentation. You’ll likely find yourself with a dissertation of over 100 pages that you’re trying to summarize in a short period of time. Work closely with your course instructor and chair to make sure you’ve addressed everything the dissertation committee is looking for in the presentation. If available, use an oral dissertation rubric as your checklist and guide to ensure you’ve answered the demands of the defense.

Create a Timeline

You have a specific time limit for your dissertation defense. Create a timeline for your presentation. Schedule out every single key point of your dissertation to ensure it’s included. Then, to make sure you adhere to your timeline, practice, practice, practice.

Be the Expert

Remember, you are now the expert on this topic. This is your research and your findings. The committee is not there to dispute your findings. They are there to engage you in scholarly conversation about what you’ve found and celebrate this momentous occasion in your academic career with you.

When you get to your dissertation defense, you’ll have been through a lot with your committee members and chair. It will be the first opportunity for your whole team to celebrate your accomplishment and contribution to your field. Revel in the hard work it took to get to this moment and enjoy it!

American College of Education provides personalized support to doctoral candidates, from the first day of your program to the last minute of your dissertation defense. Explore our fully online doctoral programs .

Top 7 tips for your defense presentation

1. show why your study is important, remember, your audience is your committee members, researchers in other fields, and even the general public. you want to convince all of them why you deserve a ph.d. degree. you need to talk about why your study is important to the world. in the engineering field, you also need to talk about how your study is useful. try to discuss why current practice is problematic or not good enough, what needs to be solved, and what the potential benefits will be. , see how dr. posen and dr. malings explained the importance of their studies..

  • Carl Malings Defense Slides with Notes
  • I. Daniel Posen Defense Slides with Notes

2. Emphasize YOUR contribution 

Having a ph.d. means that you have made some novel contributions to the grand field. this is about you and your research. you need to keep emphasizing your contributions throughout your presentation. after talking about what needs to be solved, try to focus on emphasizing the novelty of your work. what problems can be solved using your research outcomes what breakthroughs have you made to the field why are your methods and outcomes outstanding you need to incorporate answers to these questions in your presentation. , be clear what your contributions are in the introduction section; separate what was done by others and what was done by you. , 3. connect your projects into a whole piece of work, you might have been doing multiple projects that are not strongly connected. to figure out how to connect them into a whole piece, use visualizations such as flow charts to convince your audience. the two slides below are two examples. in the first slide, which was presented in the introduction section, the presenter used a flow diagram to show the connection between the three projects. in the second slide, the presenter used key figures and a unique color for each project to show the connection..

4. Tell a good story 

The committee members do not necessarily have the same background knowledge as you. plus, there could be researchers from other fields and even the general public in the room. you want to make sure all of your audience can understand as much as possible. focus on the big picture rather than technical details; make sure you use simple language to explain your methods and results. your committee has read your dissertation before your defense, but others have not. , dr. cook and dr. velibeyoglu did a good job explaining their research to everyone. the introduction sessions in their presentations are well designed for this purpose. .

  • Laren M. Cook Defense Slides with Notes
  • Irem Velibeyoglu Defense with Notes

5. Transition, transition, transition

Use transition slides to connect projects , it's a long presentation with different research projects. you want to use some sort of transition to remind your audience what you have been talking about and what is next. you may use a slide that is designed for this purpose throughout your presentation. , below are two examples. these slides were presented after the introduction section. the presenters used the same slides and highlighted the items for project one to indicate that they were moving on to the first project. throughout the presentation, they used these slides and highlighted different sections to indicate how these projects fit into the whole dissertation. .

dissertation defense advice

You can also use some other indications on your slides, but remember not to make your slides too busy.  Below are two examples. In the first example, the presenter used chapter numbers to indicate what he was talking about. In the second example, the presenter used a progress bar with keywords for each chapter as the indicator. 

dissertation defense advice

Use transition sentences to connect slides 

Remember transition sentences are also important; use them to summarize what you have said and tell your audience what they will expect next. if you keep forgetting the transition sentence, write a note on your presentation. you can either write down a full sentence of what you want to say or some keywords., 6. be brief, put details in backup slides , you won't have time to explain all of the details. if your defense presentation is scheduled for 45 minutes, you can only spend around 10 minutes for each project - that's shorter than a normal research conference presentation focus on the big picture and leave details behind. you can put the details in your backup slides, so you might find them useful when your committee (and other members of the audience) ask questions regarding these details., 7. show your presentation to your advisor and colleagues, make sure to ask your advisor(s) for their comments. they might have a different view on what should be emphasized and what should be elaborated. , you also want to practice at least once in front of your colleagues. they can be your lab mates, people who work in your research group, and/or your friends. they do not have to be experts in your field. ask them to give you some feedback - their comments can be extremely helpful to improve your presentation. , below are some other tips and resources to design your defense presentation. .

What Is a Dissertation? | Guide, Examples, & Template

Structure of a Dissertation

A dissertation is a long-form piece of academic writing based on original research conducted by you. It is usually submitted as the final step in order to finish a PhD program.

Your dissertation is probably the longest piece of writing you’ve ever completed. It requires solid research, writing, and analysis skills, and it can be intimidating to know where to begin.

Your department likely has guidelines related to how your dissertation should be structured. When in doubt, consult with your supervisor.

You can also download our full dissertation template in the format of your choice below. The template includes a ready-made table of contents with notes on what to include in each chapter, easily adaptable to your department’s requirements.

  • In the US, a dissertation generally refers to the collection of research you conducted to obtain a PhD.
  • In other countries (such as the UK), a dissertation often refers to the research you conduct to obtain your bachelor’s or master’s degree.

Table of contents

Dissertation committee and prospectus process, how to write and structure a dissertation, acknowledgements or preface, list of figures and tables, list of abbreviations, introduction, literature review, methodology, reference list, proofreading and editing, defending your dissertation, free checklist and lecture slides.

When you’ve finished your coursework, as well as any comprehensive exams or other requirements, you advance to “ABD” (All But Dissertation) status. This means you’ve completed everything except your dissertation.

Prior to starting to write, you must form your committee and write your prospectus or proposal . Your committee comprises your adviser and a few other faculty members. They can be from your own department, or, if your work is more interdisciplinary, from other departments. Your committee will guide you through the dissertation process, and ultimately decide whether you pass your dissertation defense and receive your PhD.

Your prospectus is a formal document presented to your committee, usually orally in a defense, outlining your research aims and objectives and showing why your topic is relevant . After passing your prospectus defense, you’re ready to start your research and writing.

Prevent plagiarism. Run a free check.

The structure of your dissertation depends on a variety of factors, such as your discipline, topic, and approach. Dissertations in the humanities are often structured more like a long essay , building an overall argument to support a central thesis , with chapters organized around different themes or case studies.

However, hard science and social science dissertations typically include a review of existing works, a methodology section, an analysis of your original research, and a presentation of your results , presented in different chapters.

Dissertation examples

We’ve compiled a list of dissertation examples to help you get started.

  • Example dissertation #1: Heat, Wildfire and Energy Demand: An Examination of Residential Buildings and Community Equity (a dissertation by C. A. Antonopoulos about the impact of extreme heat and wildfire on residential buildings and occupant exposure risks).
  • Example dissertation #2: Exploring Income Volatility and Financial Health Among Middle-Income Households (a dissertation by M. Addo about income volatility and declining economic security among middle-income households).
  • Example dissertation #3: The Use of Mindfulness Meditation to Increase the Efficacy of Mirror Visual Feedback for Reducing Phantom Limb Pain in Amputees (a dissertation by N. S. Mills about the effect of mindfulness-based interventions on the relationship between mirror visual feedback and the pain level in amputees with phantom limb pain).

The very first page of your document contains your dissertation title, your name, department, institution, degree program, and submission date. Sometimes it also includes your student number, your supervisor’s name, and the university’s logo.

Read more about title pages

The acknowledgements section is usually optional and gives space for you to thank everyone who helped you in writing your dissertation. This might include your supervisors, participants in your research, and friends or family who supported you. In some cases, your acknowledgements are part of a preface.

The abstract is a short summary of your dissertation, usually about 150 to 300 words long. Though this may seem very short, it’s one of the most important parts of your dissertation, because it introduces your work to your audience.

Your abstract should:

  • State your main topic and the aims of your research
  • Describe your methods
  • Summarize your main results
  • State your conclusions

Read more about abstracts

The table of contents lists all of your chapters, along with corresponding subheadings and page numbers. This gives your reader an overview of your structure and helps them easily navigate your document.

Remember to include all main parts of your dissertation in your table of contents, even the appendices. It’s easy to generate a table automatically in Word if you used heading styles. Generally speaking, you only include level 2 and level 3 headings, not every subheading you included in your finished work.

Read more about tables of contents

While not usually mandatory, it’s nice to include a list of figures and tables to help guide your reader if you have used a lot of these in your dissertation. It’s easy to generate one of these in Word using the Insert Caption feature.

Read more about lists of figures and tables

Similarly, if you have used a lot of abbreviations (especially industry-specific ones) in your dissertation, you can include them in an alphabetized list of abbreviations so that the reader can easily look up their meanings.

Read more about lists of abbreviations

In addition to the list of abbreviations, if you find yourself using a lot of highly specialized terms that you worry will not be familiar to your reader, consider including a glossary. Here, alphabetize the terms and include a brief description or definition.

Read more about glossaries

The introduction serves to set up your dissertation’s topic, purpose, and relevance. It tells the reader what to expect in the rest of your dissertation. The introduction should:

  • Establish your research topic , giving the background information needed to contextualize your work
  • Narrow down the focus and define the scope of your research
  • Discuss the state of existing research on the topic, showing your work’s relevance to a broader problem or debate
  • Clearly state your research questions and objectives
  • Outline the flow of the rest of your work

Everything in the introduction should be clear, engaging, and relevant. By the end, the reader should understand the what, why, and how of your research.

Read more about introductions

A formative part of your research is your literature review . This helps you gain a thorough understanding of the academic work that already exists on your topic.

Literature reviews encompass:

  • Finding relevant sources (e.g., books and journal articles)
  • Assessing the credibility of your sources
  • Critically analyzing and evaluating each source
  • Drawing connections between them (e.g., themes, patterns, conflicts, or gaps) to strengthen your overall point

A literature review is not merely a summary of existing sources. Your literature review should have a coherent structure and argument that leads to a clear justification for your own research. It may aim to:

  • Address a gap in the literature or build on existing knowledge
  • Take a new theoretical or methodological approach to your topic
  • Propose a solution to an unresolved problem or advance one side of a theoretical debate

Read more about literature reviews

Theoretical framework

Your literature review can often form the basis for your theoretical framework. Here, you define and analyze the key theories, concepts, and models that frame your research.

Read more about theoretical frameworks

Your methodology chapter describes how you conducted your research, allowing your reader to critically assess its credibility. Your methodology section should accurately report what you did, as well as convince your reader that this was the best way to answer your research question.

A methodology section should generally include:

  • The overall research approach ( quantitative vs. qualitative ) and research methods (e.g., a longitudinal study )
  • Your data collection methods (e.g., interviews or a controlled experiment )
  • Details of where, when, and with whom the research took place
  • Any tools and materials you used (e.g., computer programs, lab equipment)
  • Your data analysis methods (e.g., statistical analysis , discourse analysis )
  • An evaluation or justification of your methods

Read more about methodology sections

Your results section should highlight what your methodology discovered. You can structure this section around sub-questions, hypotheses , or themes, but avoid including any subjective or speculative interpretation here.

Your results section should:

  • Concisely state each relevant result together with relevant descriptive statistics (e.g., mean , standard deviation ) and inferential statistics (e.g., test statistics , p values )
  • Briefly state how the result relates to the question or whether the hypothesis was supported
  • Report all results that are relevant to your research questions , including any that did not meet your expectations.

Additional data (including raw numbers, full questionnaires, or interview transcripts) can be included as an appendix. You can include tables and figures, but only if they help the reader better understand your results. Read more about results sections

Your discussion section is your opportunity to explore the meaning and implications of your results in relation to your research question. Here, interpret your results in detail, discussing whether they met your expectations and how well they fit with the framework that you built in earlier chapters. Refer back to relevant source material to show how your results fit within existing research in your field.

Some guiding questions include:

  • What do your results mean?
  • Why do your results matter?
  • What limitations do the results have?

If any of the results were unexpected, offer explanations for why this might be. It’s a good idea to consider alternative interpretations of your data.

Read more about discussion sections

Your dissertation’s conclusion should concisely answer your main research question, leaving your reader with a clear understanding of your central argument and emphasizing what your research has contributed to the field.

In some disciplines, the conclusion is just a short section preceding the discussion section, but in other contexts, it is the final chapter of your work. Here, you wrap up your dissertation with a final reflection on what you found, with recommendations for future research and concluding remarks.

It’s important to leave the reader with a clear impression of why your research matters. What have you added to what was already known? Why is your research necessary for the future of your field?

Read more about conclusions

It is crucial to include a reference list or list of works cited with the full details of all the sources that you used, in order to avoid plagiarism. Be sure to choose one citation style and follow it consistently throughout your dissertation. Each style has strict and specific formatting requirements.

Common styles include MLA , Chicago , and APA , but which style you use is often set by your department or your field.

Create APA citations Create MLA citations

Your dissertation should contain only essential information that directly contributes to answering your research question. Documents such as interview transcripts or survey questions can be added as appendices, rather than adding them to the main body.

Read more about appendices

Making sure that all of your sections are in the right place is only the first step to a well-written dissertation. Don’t forget to leave plenty of time for editing and proofreading, as grammar mistakes and sloppy spelling errors can really negatively impact your work.

Dissertations can take up to five years to write, so you will definitely want to make sure that everything is perfect before submitting. You may want to consider using a professional dissertation editing service , AI proofreader or grammar checker to make sure your final project is perfect prior to submitting.

After your written dissertation is approved, your committee will schedule a defense. Similarly to defending your prospectus, dissertation defenses are oral presentations of your work. You’ll present your dissertation, and your committee will ask you questions. Many departments allow family members, friends, and other people who are interested to join as well.

After your defense, your committee will meet, and then inform you whether you have passed. Keep in mind that defenses are usually just a formality; most committees will have resolved any serious issues with your work with you far prior to your defense, giving you ample time to fix any problems.

As you write your dissertation, you can use this simple checklist to make sure you’ve included all the essentials.

It is an oral presentation where you will also be addressing questions that the committee may have about your work and how it can contribute to the field that you are studying.

Remember, your dissertation paper has already been reviewed by this point. The presentation is the committee’s way of understanding what you learned while putting it together. They also assess if the student is ready to take on the roles and responsibilities of a scholar. For doctoral candidates, this is an opportunity to explain what they did and the results that they obtained. Think of it as a final step before you step into the academic world.

How Long Is A Dissertation Defense?

On average, set aside at least 2 hours for your dissertation presentation. Remember to factor in the time that you take to prepare and warm up to the committee, present the actual defense and then complete a round of questions with them.

Sometimes, the defense can be over in as little as 20 minutes. It is necessary to understand that the duration of the defense is not a mark of its quality. As long as you are able to confidently defend your paper and keep the committee involved, you can consider it a successful dissertation defense presentation.

How long does a dissertation defense last? This is a question on the minds of most doctoral students. The answer to this is varied as it vastly depends upon the field of study and the nature of your topic.

How to Prepare For the Dissertation Defense?

Now we come to the most important question, how to prepare for dissertation defense? The good news is that you will have ample time to get all your material together and practice. Here are some tips that have always helped students do their best on the final day:

Attend As Many Conferences As Possible

There are several academic conferences where you will get a chance to present your work. This is the best exercise to practice for your final defense of dissertation. The advantage of these conferences is that you will be able to address an international and mixed audience. You also get good feedback that you can use to improve your defense presentation. Besides conferences, industry events and workshops are great opportunities for you to get used to being on stage and addressing people.

Know Your Committee

During your dissertation defense proposal, the interaction is limited to you and your committee. So, it helps to know who you will be presenting to. Learn about the work of your dissertation defense committee so that you can evaluate your presentation through their eyes. Read their latest papers and publications to stay updated about their work. This will also help if your committee members have worked on similar topics and may direct related questions to you. It helps to meet your committee members before the presentation if you have the opportunity. Make notes during these meetings and identify the points that they criticized. Using this information, prepare 5-10 dissertation defense questions that they may ask you.

Go Through All the Important Papers

The questions that the committee presents to you will be related to all the work in your field. So, it is important to stay current and updated with the publications and research papers that already exist. It is a good idea for you to go through papers related to your work and the work of the committee.

This will give you a great foundation to answer questions. When you are reviewing the available research, you can also explore some subjects outside the primary focus of your work. Think of papers on various fields of application, the broader scope of your subject, and future applications. This will help you be completely prepared for any questions that your committee may throw at you. Make sure that you practice short, crisp, and smart answers to questions that you think the committee may ask you based on the information you get after reviewing available papers and publications.

Prepare an Organized PowerPoint Presentation

A PowerPoint presentation is an important tool to keep you focused on the important subjects during the dissertation defense. This presentation also comes handy when you are presenting your work to the faculty of any University that you plan to apply to in the future. Make sure that the template of your presentation is simple. You must also make sure that it is not too wordy and lengthy. Think of short sentences and keywords that provide:

  • A quick overview of the literature that your paper is based on
  • A clear understanding of the purpose of the study.
  • Details of the findings of your research
  • The implications of the results that you have arrived at.

Make sure you speak to your department and professors to understand the exact flow of the presentation. The requirements vary from one university to another. However, the points mentioned above are of prime interest to your committee as they cover the most important elements of your work.

Practice Before You Present

The more you practice before your PhD dissertation defense, the better you will be at delivering it. Once your dissertation proposal defense PowerPoint is complete, stand before a mirror and present it like you would on the final day. Pay attention to your body language and the pronunciation of the words, especially important jargons and terms. Here are some tips to help you practice better:

  • Keep your body language more open. This means your arms must be more relaxed and open.
  • Avoid moving your arms too much as it is a sign of nervousness.
  • Make sure you pause to breathe at the right time.
  • The posture of your body should be relaxed, yet confident.
  • Try to be as expressive when necessary.
  • Vary the tone of your voice to emphasize on important points of the dissertation defense.
  • Speak slowly and clearly.

It helps to watch dissertation defense presentations by students who have already completed their PhD. There are several videos available online that can help you understand the right way to present yourself before a committee.

Get To Know The Room

You will be assigned a conference hall well in advance. Pay a visit and take a look at the tools and facilities available in the room. This will help you understand what material you need. For instance, do you need to carry your laptop with you or should you hand it over on a pen drive? Of course, have both options ready on the final day, just in case.

You will also get an idea about how the committee will be seated during the presentation. You can practice your movements according to that. The added advantage to knowing the room you will be presenting in is that you can visualize yourself in it every time you practice. Then, when you are actually presenting the defense, the room will feel more familiar and comfortable.

Dissertation Defense Tips

Now that you understand the process of preparing for dissertation defense, here are some tips that will help you deliver it well:

  • Presentation matters: The first impression that you make leads the entire presentation. You want to look smart, confident and ready to take on any questions that the committee may have for you. So, what to wear to a dissertation defense? Simple formal clothing is the best way to go. To add a touch of your personality, you can include a quirky tie, a family hair loom or any other element that is not too distracting. Make sure you get a thorough grooming session before your presentation so that you look fresh, despite the long hours of working and preparing for your dissertation defense.
  • Prepare yourself mentally: This is the most important step when it comes to defending your dissertation. Make sure that you go in with the right attitude. Think of different ways to calm your nerves before you step into the presentation room. A few breathing exercises help immensely. Also, remember that you have prepared well and are ready to face the committee. It also helps to know that the committee is on your side. They are not out to get you and want to ensure that you get the best outcome as well.
  • Always maintain eye contact during the presentation: This is very important to show that you feel confident about defending your dissertation. Look at each member of the committee during the presentation. Do not stay focused on your PowerPoint or reading material as it can be very distracting.
  • Answer questions to the point: Whenever you are asked a question by a committee member, make sure that your answer is to the point. Do not draw any tangents or parallels just to prove your point. The more you divert, the less prepared you seem.
  • Be open to discussion and criticism: Sometimes, a committee member may not agree with your results or approach. You do not have to accept your mistake or agree with him or her. Instead, explain why you chose the other direction and ask for their opinion on that. This impresses them more as it shows your critical thinking ability. It also shows one of the best qualities of a scholar, which is being able to engage in open dialogue and discussion.

Why Is Dissertation Defense Important?

The dissertation is one of the most important papers during your doctoral degree. It is a test of your capabilities as a researcher. The dissertation defense proposal reiterates your understanding of the subject that you have chosen and, more importantly, your field of study. It is also a great opportunity for you to present your work. This is what you have been working on through the course and sharing the findings is an exhilarating experience.

17 Thesis Defense Questions and How to Answer Them

EditrixJD

A thesis defense gives you the chance to show off your thesis work and demonstrate your expertise in your field of study. During this one- to two-hour discussion with the members of your thesis committee, you'll have some control over how you present your research, but your committee will ask you some prodding questions to test your knowledge and preparedness. They will all have read your thesis beforehand, so their questions will relate to your study, topic, methods, data sample, and other aspects.

A good defense requires mastery of the thesis itself, so before you consider the questions you might face,

1. What is your topic, and why did you choose it?

Give a quick summary in just a few sentences on what you've researched. You could certainly go on for hours about your work, but make sure you prepare a way to give a very brief overview of your thesis. Then, give a quick background on your process for choosing this topic.

2. How does your topic contribute to the existing literature? How is it important?

Many researchers identify a need in the field and choose a topic to bridge the gaps that previous literature has failed to cover. For example, previous studies might not have included a certain population, region, or circumstance. Talk about how your thesis enhances the general understanding of the topic to extend the reach beyond what others have found, and then give examples of why the world needs that increased understanding. For instance, a thesis on romaine lettuce crops in desert climates might bring much-needed knowledge to a region that might not have been represented in previous work.

3. What are the key findings of your study?

When reporting your main results, make sure you have a handle on how detailed your committee wants you to be. Give yourself several options by preparing 1) a very general, quick summary of your findings that takes a minute or less, 2) a more detailed rundown of what your study revealed that is 3-5 minutes long, and 3) a 10- to 15-minute synopsis that delves into your results in detail. With each of these responses prepared, you can gauge which one is most appropriate in the moment, based on what your committee asks you and what has already been requested.

4. What type of background research did you do for your study?

Here you'll describe what you did while you were deciding what to study. This usually includes a literary review to determine what previous researchers have already introduced to the field. You also likely had to look into whether your study was going to be possible and what you would need in order to collect the needed data. Did you need info from databases that require permissions or fees?

5. What was your hypothesis, and how did you form it?

Describe the expected results you had for your study and whether your hypothesis came from previous research experience, long-held expectations, or cultural myths.

6. What limitations did you face when writing your text?

It's inevitable — researchers will face roadblocks or limiting factors during their work. This could be a limited population you had access to, like if you had a great method of surveying university students, but you didn't have a way to reach out to other people who weren't attending that school.

7. Why did you choose your particular method for your study?

Different research methods are more fitting to specific studies than others (e.g., qualitative vs. quantitative ), and knowing this, you applied a method that would present your findings most effectively. What factors led you to choose your method?

8. Who formed the sample group of your study, and why did you choose this population?

Many factors go into the selection of a participant group. Perhaps you were motivated to survey women over 50 who experience burnout in the workplace. Did you take extra measures to target this population? Or perhaps you found a sample group that responded more readily to your request for participation, and after hitting dead ends for months, convenience is what shaped your study population. Make sure to present your reasoning in an honest but favorable way.

9. What obstacles or limitations did you encounter while working with your sample?

Outline the process of pursuing respondents for your study and the difficulties you faced in collecting enough quality data for your thesis. Perhaps the decisions you made took shape based on the participants you ended up interviewing.

10. Was there something specific you were expecting to find during your analysis?

Expectations are natural when you set out to explore a topic, especially one you've been dancing around throughout your academic career. This question can refer to your hypotheses , but it can also touch on your personal feelings and expectations about this topic. What did you believe you would find when you dove deeper into the subject? Was that what you actually found, or were you surprised by your results?

11. What did you learn from your study?

Your response to this question can include not only the basic findings of your work (if you haven't covered this already) but also some personal surprises you might have found that veered away from your expectations. Sometimes these details are not included in the thesis, so these details can add some spice to your defense.

12. What are the recommendations from your study?

With connection to the reasons you chose the topic, your results can address the problems your work is solving. Give specifics on how policymakers, professionals in the field, etc., can improve their service with the knowledge your thesis provides.

13. If given the chance, what would you do differently?

Your response to this one can include the limitations you encountered or dead ends you hit that wasted time and funding. Try not to dwell too long on the annoyances of your study, and consider an area of curiosity; for example, discuss an area that piqued your interest during your exploration that would have been exciting to pursue but didn't directly benefit your outlined study.

14. How did you relate your study to the existing theories in the literature?

Your paper likely ties your ideas into those of other researchers, so this could be an easy one to answer. Point out how similar your work is to some and how it contrasts other works of research; both contribute greatly to the overall body of research.

15. What is the future scope of this study?

This one is pretty easy, since most theses include recommendations for future research within the text. That means you already have this one covered, and since you read over your thesis before your defense, it's already fresh in your mind.

16. What do you plan to do professionally after you complete your study?

This is a question directed more to you and your future professional plans. This might align with the research you performed, and if so, you can direct your question back to your research, maybe mentioning the personal motivations you have for pursuing study of that subject.

17. Do you have any questions?

Although your thesis defense feels like an interrogation, and you're the one in the spotlight, it provides an ideal opportunity to gather input from your committee, if you want it. Possible questions you could ask are: What were your impressions when reading my thesis? Do you believe I missed any important steps or details when conducting my work? Where do you see this work going in the future?

Bonus tip: What if you get asked a question to which you don't know the answer? You can spend weeks preparing to defend your thesis, but you might still be caught off guard when you don't know exactly what's coming. You can be ready for this situation by preparing a general strategy. It's okay to admit that your thesis doesn't offer the answers to everything – your committee won't reasonably expect it to do so. What you can do to sound (and feel!) confident and knowledgeable is to refer to a work of literature you have encountered in your research and draw on that work to give an answer. For example, you could respond, "My thesis doesn't directly address your question, but my study of Dr. Leifsen's work provided some interesting insights on that subject…." By preparing a way to address curveball questions, you can maintain your cool and create the impression that you truly are an expert in your field.

After you're done answering the questions your committee presents to you, they will either approve your thesis or suggest changes you should make to your paper. Regardless of the outcome, your confidence in addressing the questions presented to you will communicate to your thesis committee members that you know your stuff. Preparation can ease a lot of anxiety surrounding this event, so use these possible questions to make sure you can present your thesis feeling relaxed, prepared, and confident.
