How to Choose a Dissertation Topic

A doctoral degree is often the choice for those eager to delve deeply into their academic passions within a research-intensive framework. Such programs span several years, encompassing both coursework and extensive research phases, leading to the defense of a pivotal piece: the dissertation. This guide will provide guidance on what a dissertation involves and how to choose a dissertation topic for your research.

What Is a Dissertation?

A dissertation or thesis is a culmination of years of study, encapsulating your grasp on a subject and your ability to contribute original research to your field. The project requires planning, research, analysis, and significant time and dedication. A dissertation is the pinnacle of one’s academic career, representing a transition from student to expert.

As highlighted by Top Universities, a dissertation is an in-depth research endeavor that entails aggregating and assessing fresh or pre-existing data. Drawing upon the techniques and protocols instilled during your doctoral journey, you’re expected to present data and effectively showcase your discoveries in your dissertation.

How to Choose a Dissertation Topic

The core of your dissertation lies in its topic. Here’s a step-by-step guide to help you narrow your choices and select a good topic for your dissertation.

Step 1: Check the Requirements

Each university or department has its unique set of guidelines. These can range from strict dissertation or thesis topic boundaries to more flexible suggestions. Understanding these rules is imperative, as they serve as the blueprint for your dissertation journey. Some institutions might restrict research topics based on available resources, faculty expertise, or ongoing departmental projects. It’s not just about what you want to research but also what’s feasible within the scope of your program.

Some universities may provide specific themes or subjects they’re keen to explore further. These often align with the institution’s strengths, current research trends, or pressing global issues. Tapping into these themes can offer additional support, as they’re often backed by experienced faculty or well-established research groups. By understanding the requirements, you can avoid choosing a topic that’s already been extensively covered in your department. 

Step 2: Choose a Broad Field of Research

Choosing a good dissertation topic often involves zooming out to view the larger academic landscape. Which courses or subjects resonated with you the most? Which topics made your heart race a bit faster or sparked that fire of curiosity? This self-reflection is the cornerstone of genuine passion and can guide your overarching research direction.

While your area of interest is paramount, it’s also wise to gauge the current trends in your chosen field to ensure your research remains relevant and contributes meaningfully to contemporary academic discourse. When writing a dissertation, consult with mentors or professors as their experience can provide insights into fields with rich research potential or those that align well with departmental strengths.

Consider the post-dissertation future. Does your chosen broad field align with your career aspirations? If you’re looking towards academia, a thriving and expansive field might offer more opportunities. Alternatively, if you’re eyeing the corporate or non-profit sector, fields with practical implications could be more beneficial. Sometimes, the magic happens at the intersection of disciplines.

Step 3: Look for Books and Articles

Beginning with preliminary readings allows you to construct a holistic image of your chosen topic. You’ll understand major theories, key figures, controversial debates, and emerging trends. Explore libraries and refer to books, journals, periodicals, and, sometimes, rare manuscripts. Most university libraries have extensive collections specific to their departments’ strengths.

Online databases like JSTOR, Google Scholar, and PubMed offer vast repositories of articles, journals, conference papers, and more. Advanced search filters allow you to find resources aligned with your broad field, ensuring you remain abreast of the latest findings. Subscribing to or browsing key academic journals and magazines can be enlightening. 

As you progress in your research journey, it’s crucial to maintain this literature exploration. New publications or breakthroughs could reshape your field’s landscape, and staying updated ensures your research remains relevant.

Step 4: Find a Niche

While building upon existing literature is essential, introducing a fresh perspective or addressing an unresolved query can set your work apart. Scrutinize studies for limitations, areas they haven’t explored, or assumptions made. Authors often hint at potential future research directions in their discussions or conclusions. Relating your research to current events or pressing global challenges can provide a fresh angle. 

Discuss with peers, mentors, or even experts outside your field. These interactions can offer fresh perspectives, question your assumptions, or even point out areas you might have missed. Academic conferences, seminars, or workshops can be goldmines for enriching dialogues. Your topic should be specific enough to offer depth but broad enough to warrant comprehensive exploration. 

Choosing a niche you’re passionate about fuels perseverance, especially during challenging phases. Consider how it might evolve in the future. Does it have the potential to open doors for further research? Can it lead to practical applications or policy changes? Forecasting these implications can add depth to your work.

Step 5: Consider the Type of Research

Understanding the nature of your research methodology, whether qualitative, quantitative, or even a mixed-method approach, shapes the direction and depth of your dissertation. Find a topic with methods that relate with your subject matter, research questions, and personal strengths.

Qualitative research primarily explores and understands underlying motivations, opinions, or reasons. Quantitative research seeks to quantify data and, typically, apply some form of statistical analysis. It’s about drawing general conclusions from measurable data. Combining both qualitative and quantitative research can sometimes provide a more holistic perspective. It capitalizes on the strengths of both approaches while compensating for their individual shortcomings.

Step 6: Determine the Relevance

A relevant topic is more likely to capture your academic peers’ interest and increase your work’s impact within the broader field.  Regularly scouring top-tier academic journals can offer a pulse on the latest studies, debates, and unresolved questions. Conferences and seminars often spotlight pressing or emerging issues. Listening to discussions and keynote speeches can provide a wealth of inspiration. Platforms like ResearchGate or specific subreddits can be platforms where professionals debate, discuss, and share insights.

Topics like climate change, mental health, digital privacy, and socioeconomic disparities resonate globally. If your research intersects with such topics, it immediately amplifies its relevance. Engaging in some forecasting can help you anticipate areas that’ll become more significant in the future, placing you ahead of the curve. While external relevance is essential, internal resonance shouldn’t be overlooked. If a topic deeply matters to you, your passion can translate into a more engaged and thorough research process.

Step 7: Make Sure it’s Plausible

Consider the budgetary requirements. Will you need to purchase specific equipment, software, or database access? Are there travel costs or fees for accessing certain archives or facilities? Ensure all materials – books, archives, samples, or software – are readily accessible. Some topics might sound intriguing but could be handcuffed by unavailable resources.

Some research might demand prolonged data collection periods, such as longitudinal studies or observing rare events. A topic requiring intricate data analysis techniques might consume more time than anticipated. Being realistic about the time required for each phase of research is crucial. Break your dissertation into smaller tasks with deadlines. It provides a visual representation of feasibility in terms of time constraints.

If your research demands fieldwork, ensure the locations are accessible and safe. In health or social research, ethical considerations might affect feasibility. Acquiring permissions or clearances can sometimes be time-consuming. Should your topic require expert interviews, ensure these individuals are approachable and available.

Step 8: Get your Topic Approved

Start with a clear statement of your topic. It should be easy to grasp but compelling enough to spark interest. Outline the primary objectives of your research and the key questions you aim to answer. Briefly explain the methods you intend to employ, whether qualitative, quantitative, or mixed approach. Present a snapshot of the existing literature that inspired your topic, highlighting gaps your research seeks to address.

Schedule a formal meeting by giving your supervisor ample time to review your proposal before the meeting. This ensures they come prepared with insights and feedback. Consider creating a brief presentation. Visual aids can help clarify complex ideas and show your commitment and preparation. Enter the meeting with an open mind. While you’ve invested heavily in your topic, be receptive to critiques—they aim to refine, not negate, your ideas.

Use this opportunity to seek clarity on any concerns you have. Your supervisor’s experiences can offer valuable shortcuts and insights. If your supervisor suggests changes, take the time to understand their perspective and make the necessary revisions thoroughly. Keep your supervisor in the loop. Regularly update them about any alterations or developments in your topic.

In some academic institutions, a committee must approve dissertation topics. Understanding the interests and preferences of committee members can help you pitch your topic effectively. Once verbally approved, there might be formal paperwork or online systems through which official approval is granted. Ensure you’re familiar with these processes. Having a backup topic or a variant of your original idea is wise. Having a contingency can save time and stress if there are unforeseen issues with your primary choice.

Does Your Dissertation Topic Matter After You Graduate?

Given the magnitude of effort and time a dissertation demands, you must contemplate how the theme might affect your professional future. Should your aspirations involve lecturing at a higher educational tier or extending your studies, the focus of your dissertation will inevitably pave the way for your teaching and research endeavors. 

This perspective, as emphasized by Francesco Lelli, represents one end while the other suggests its relevance may not matter post-graduation. Lelli delineates seven potential outcomes your dissertation could result in upon completing your studies.

• Your thesis will be (almost) forgotten
• Your thesis will be used by another student
• A student association will use your thesis
• Your thesis will contribute to the research of your supervisor
• You will co-author a publication that uses part of the content of your thesis
• Your thesis will contribute to some national or international research project
• Your thesis will be used in the company where you were doing your internship

How Long Is a Dissertation?

The length of a dissertation is around 10,000 to 12,000 words at the undergraduate level. These projects provide students with their first taste of independent research, allowing them to explore a particular area of their discipline. While shorter than their postgraduate counterparts, they still include essential sections like the introduction, abstract, preface, literature review, methodology, results, acknowledgements and conclusion.

For most master’s programs, dissertations tend to hover between 15,000 to 25,000 words. Unlike undergraduate projects, master’s dissertations require a more in-depth exploration of the chosen topic. The expectation here is for students to showcase a mastery of the subject.

Doctoral dissertations are more exhaustive in nature, typically ranging from 50,000 words to over 100,000 in some cases. Ph.D. candidates are expected to make a novel contribution to their field. This often requires comprehensive research, experimentation, and analysis, leading to a longer dissertation. Given the extensive nature of the research, Ph.D. dissertations have more sections.

Final Thoughts on Choosing a Dissertation Topic

Choosing a dissertation topic is a significant step in your academic journey. It’s an opportunity to showcase your passion, knowledge, and research skills. While the process can be challenging, the outcome can be incredibly rewarding, setting the foundation for your future in the academic and professional world.
