• How to Choose a PhD Research Topic
• Finding a PhD

Introduction

Whilst there are plenty of resources available to help prospective PhD students find doctoral programmes, deciding on a research topic is a process students often find more difficult.

Some advertised PhD programmes have predefined titles, so the exact topic is decided already. Generally, these programmes exist mainly in STEM, though other fields also have them. Funded projects are more likely to have defined titles, and structured aims and objectives.

Self funded projects, and those in fields such as arts and humanities, are less likely to have defined titles. The flexibility of topic selection means more scope exists for applicants to propose research ideas and suit the topic of research to their interests.

A middle ground also exists where Universities advertise funded PhD programmes in subjects without a defined scope, for example: “PhD Studentship in Biomechanics”. The applicant can then liaise with the project supervisor to choose a particular title such as “A study of fatigue and impact resistance of biodegradable knee implants”.

If a predefined programme is not right for you, then you need to propose your own research topic. There are several factors to consider when choosing a good research topic, which will be outlined in this article.

How to Choose a Research Topic

Our first piece of advice is to PhD candidates is to stop thinking about ‘finding’ a research topic, as it is unlikely that you will. Instead, think about developing a research topic (from research and conversations with advisors).

Consider several ideas and critically appraise them:

• You must be able to explain to others why your chosen topic is worth studying.
• You must be genuinely interested in the subject area.
• You must be competent and equipped to answer the research question.
• You must set achievable and measurable aims and objectives.
• You need to be able to achieve your objectives within a given timeframe.
• Your research question must be original and contribute to the field of study.

We have outlined the key considerations you should use when developing possible topics. We explore these below:

Focus on your interests and career aspirations

It is important to choose a topic of research that you are genuinely interested in. The decision you make will shape the rest of your career. Remember, a full-time programme lasts 3-4 years, and there will be unforeseen challenges during this time. If you are not passionate about the study, you will struggle to find motivation during these difficult periods.

You should also look to your academic and professional background. If there are any modules you undertook as part of your Undergraduate/Master degree that you particularly enjoyed or excelled in? These could form part of your PhD research topic. Similarly, if you have professional work experience, this could lead to you asking questions which can only be answered through research.

When deciding on a PhD research topic you should always consider your long-term career aspirations. For example, as a physicist, if you wish to become an astrophysicist, a research project studying black holes would be more relevant to you than a research project studying nuclear fission.

Read dissertations and published journals

Reading dissertations and published journals is a great way to identify potential PhD topics. When reviewing existing research ask yourself:

• What has been done and what do existing results show?
• What did previous projects involve (e.g. lab-work or fieldwork)?
• How often are papers published in the field?
• Are your research ideas original?
• Is there value in your research question?
• Could I expand on or put my own spin on this research?

Reading dissertations will also give you an insight into the practical aspects of doctoral study, such as what methodology the author used, how much data analysis was required and how was information presented.

You can also think of this process as a miniature literature review . You are searching for gaps in knowledge and developing a PhD project to address them. Focus on recent publications (e.g. in the last five years). In particular, the literature review of recent publications will give an excellent summary of the state of existing knowledge, and what research questions remain unanswered.

If you have the opportunity to attend an academic conference, go for it! This is often an excellent way to find out current theories in the industry and the research direction. This knowledge could reveal a possible research idea or topic for further study.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

Discuss research topic ideas with a PhD supervisor

Discuss your research topic ideas with a supervisor. This could be your current undergraduate/masters supervisor, or potential supervisors of advertised PhD programmes at different institutions. Come to these meetings prepared with initial PhD topic ideas, and your findings from reading published journals. PhD supervisors will be more receptive to your ideas if you can demonstrate you have thought about them and are committed to your research.

You should discuss your research interests, what you have found through reading publications, and what you are proposing to research. Supervisors who have expertise in your chosen field will have insight into the gaps in knowledge that exist, what is being done to address them, and if there is any overlap between your proposed research ideas and ongoing research projects.

Talking to an expert in the field can shape your research topic to something more tangible, which has clear aims and objectives. It can also find potential shortfalls of your PhD ideas.

It is important to remember, however, that although it is good to develop your research topic based on feedback, you should not let the supervisor decide a topic for you. An interesting topic for a supervisor may not be interesting to you, and a supervisor is more likely to advise on a topic title which lends itself to a career in academia.

Another tip is to talk to a PhD student or researcher who is involved in a similar research project. Alternatively, you can usually find a relevant research group within your University to talk to. They can explain in more detail their experiences and suggest what your PhD programme could involve with respect to daily routines and challenges.

Look at advertised PhD Programmes

Use our Search tool , or look on University PhD listing pages to identify advertised PhD programmes for ideas.

• What kind of PhD research topics are available?
• Are these similar to your ideas?
• Are you interested in any of these topics?
• What do these programmes entail?

The popularity of similar PhD programmes to your proposed topic is a good indicator that universities see value in the research area. The final bullet point is perhaps the most valuable takeaway from looking at advertised listings. Review what similar programmes involve, and whether this is something you would like to do. If so, a similar research topic would allow you to do this.

Writing a Research Proposal

As part of the PhD application process , you may be asked to summarise your proposed research topic in a research proposal. This is a document which summarises your intended research and will include the title of your proposed project, an Abstract, Background and Rationale, Research Aims and Objectives, Research Methodology, Timetable, and a Bibliography. If you are required to submit this document then read our guidance on how to write a research proposal for your PhD application.

Selecting a right topic of your research – Why is it important?

Too ambitious a topic can lead to delays in completing your research work and also require external funds to complete. Too easy a topic of research may lead to rejections when conducting your research or even can become difficult to defend when committee asks for unique contribution of your research.

An appropriate topic leads to a good PhD Proposal or Synopsis

If the topic is selected without collecting enough scientific evidence or journal papers, the resulting PhD proposal or synopsis will also have no impact. This will lead to rejections and poor structure of research.

Topic Selection – 3 tips to follow

These three tips will ensure that you do not select any topic but select a research topic which is challenging yet viable to complete in stipulated time.

a) Look for minimum 10 references which relate to your research topic however, do not exactly address your problem statement. Mention this as your source for selection of topic.

b) Google your topic and search specifically on ResearchGate, Google Scholar to ensure that there is no direct match of your topic.

c) Do not try to include a lot of aspects of your research in your topic. Topic is a brief statement of your title of research.

How to Choose a Dissertation Topic | 8 Steps to Follow

Published on November 11, 2022 by Shona McCombes and Tegan George. Revised on November 20, 2023.

Choosing your dissertation topic is the first step in making sure your research goes as smoothly as possible. When choosing a topic, it’s important to consider:

• Your institution and department’s requirements
• Your areas of knowledge and interest
• The scientific, social, or practical relevance
• The availability of data and resources
• The timeframe of your dissertation
• The relevance of your topic

You can follow these steps to begin narrowing down your ideas.

Table of contents

Step 1: check the requirements, step 2: choose a broad field of research, step 3: look for books and articles, step 4: find a niche, step 5: consider the type of research, step 6: determine the relevance, step 7: make sure it’s plausible, step 8: get your topic approved, other interesting articles, frequently asked questions about dissertation topics.

The very first step is to check your program’s requirements. This determines the scope of what it is possible for you to research.

• Is there a minimum and maximum word count?
• When is the deadline?
• Should the research have an academic or a professional orientation?
• Are there any methodological conditions? Do you have to conduct fieldwork, or use specific types of sources?

Some programs have stricter requirements than others. You might be given nothing more than a word count and a deadline, or you might have a restricted list of topics and approaches to choose from. If in doubt about what is expected of you, always ask your supervisor or department coordinator.

Start by thinking about your areas of interest within the subject you’re studying. Examples of broad ideas include:

• Twentieth-century literature
• Economic history
• Health policy

To get a more specific sense of the current state of research on your potential topic, skim through a few recent issues of the top journals in your field. Be sure to check out their most-cited articles in particular. For inspiration, you can also search Google Scholar , subject-specific databases , and your university library’s resources.

As you read, note down any specific ideas that interest you and make a shortlist of possible topics. If you’ve written other papers, such as a 3rd-year paper or a conference paper, consider how those topics can be broadened into a dissertation.

After doing some initial reading, it’s time to start narrowing down options for your potential topic. This can be a gradual process, and should get more and more specific as you go. For example, from the ideas above, you might narrow it down like this:

• Twentieth-century literature   Twentieth-century Irish literature   Post-war Irish poetry
• Economic history   European economic history   German labor union history
• Health policy   Reproductive health policy   Reproductive rights in South America

All of these topics are still broad enough that you’ll find a huge amount of books and articles about them. Try to find a specific niche where you can make your mark, such as: something not many people have researched yet, a question that’s still being debated, or a very current practical issue.

At this stage, make sure you have a few backup ideas — there’s still time to change your focus. If your topic doesn’t make it through the next few steps, you can try a different one. Later, you will narrow your focus down even more in your problem statement and research questions .

There are many different types of research , so at this stage, it’s a good idea to start thinking about what kind of approach you’ll take to your topic. Will you mainly focus on:

• Collecting original data (e.g., experimental or field research)?
• Analyzing existing data (e.g., national statistics, public records, or archives)?
• Interpreting cultural objects (e.g., novels, films, or paintings)?
• Comparing scholarly approaches (e.g., theories, methods, or interpretations)?

Many dissertations will combine more than one of these. Sometimes the type of research is obvious: if your topic is post-war Irish poetry, you will probably mainly be interpreting poems. But in other cases, there are several possible approaches. If your topic is reproductive rights in South America, you could analyze public policy documents and media coverage, or you could gather original data through interviews and surveys .

You don’t have to finalize your research design and methods yet, but the type of research will influence which aspects of the topic it’s possible to address, so it’s wise to consider this as you narrow down your ideas.

It’s important that your topic is interesting to you, but you’ll also have to make sure it’s academically, socially or practically relevant to your field.

• Academic relevance means that the research can fill a gap in knowledge or contribute to a scholarly debate in your field.
• Social relevance means that the research can advance our understanding of society and inform social change.
• Practical relevance means that the research can be applied to solve concrete problems or improve real-life processes.

The easiest way to make sure your research is relevant is to choose a topic that is clearly connected to current issues or debates, either in society at large or in your academic discipline. The relevance must be clearly stated when you define your research problem .

Before you make a final decision on your topic, consider again the length of your dissertation, the timeframe in which you have to complete it, and the practicalities of conducting the research.

Will you have enough time to read all the most important academic literature on this topic? If there’s too much information to tackle, consider narrowing your focus even more.

Will you be able to find enough sources or gather enough data to fulfil the requirements of the dissertation? If you think you might struggle to find information, consider broadening or shifting your focus.

Do you have to go to a specific location to gather data on the topic? Make sure that you have enough funding and practical access.

Last but not least, will the topic hold your interest for the length of the research process? To stay motivated, it’s important to choose something you’re enthusiastic about!

Most programmes will require you to submit a brief description of your topic, called a research prospectus or proposal .

Remember, if you discover that your topic is not as strong as you thought it was, it’s usually acceptable to change your mind and switch focus early in the dissertation process. Just make sure you have enough time to start on a new topic, and always check with your supervisor or department.

If you want to know more about the research process , methodology , research bias , or statistics , make sure to check out some of our other articles with explanations and examples.

Methodology

• Sampling methods
• Simple random sampling
• Stratified sampling
• Cluster sampling
• Likert scales
• Reproducibility

 Statistics

• Null hypothesis
• Statistical power
• Probability distribution
• Effect size
• Poisson distribution

Research bias

• Optimism bias
• Cognitive bias
• Implicit bias
• Hawthorne effect
• Anchoring bias
• Explicit bias

Formulating a main research question can be a difficult task. Overall, your question should contribute to solving the problem that you have defined in your problem statement .

However, it should also fulfill criteria in three main areas:

• Researchability
• Feasibility and specificity
• Relevance and originality

All research questions should be:

• Focused on a single problem or issue
• Researchable using primary and/or secondary sources
• Feasible to answer within the timeframe and practical constraints
• Specific enough to answer thoroughly
• Complex enough to develop the answer over the space of a paper or thesis
• Relevant to your field of study and/or society more broadly

You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.

Ask questions such as:

• Who is the author? Are they an expert?
• Why did the author publish it? What is their motivation?
• How do they make their argument? Is it backed up by evidence?

A dissertation prospectus or proposal describes what or who you plan to research for your dissertation. It delves into why, when, where, and how you will do your research, as well as helps you choose a type of research to pursue. You should also determine whether you plan to pursue qualitative or quantitative methods and what your research design will look like.

It should outline all of the decisions you have taken about your project, from your dissertation topic to your hypotheses and research objectives , ready to be approved by your supervisor or committee.

Note that some departments require a defense component, where you present your prospectus to your committee orally.

The best way to remember the difference between a research plan and a research proposal is that they have fundamentally different audiences. A research plan helps you, the researcher, organize your thoughts. On the other hand, a dissertation proposal or research proposal aims to convince others (e.g., a supervisor, a funding body, or a dissertation committee) that your research topic is relevant and worthy of being conducted.
