Choose a dissertation topic by identifying a subject you find genuinely interesting, checking it is feasible within your time and resource limits, and confirming with your supervisor that it offers scope for original research.
Start broad, then narrow your focus by reading recent journal articles and identifying gaps or debates in the literature that a dissertation could address. A topic that is too wide often leads to a weak, unfocused argument.
Check practical constraints early: can you access the data, participants, or archives you need within your timeframe? Many strong topic ideas are rejected at proposal stage simply because the research was not realistically achievable.
Once you have a working title, refine it into two or three specific research questions, since a vague topic makes planning your dissertation far harder later. Discuss draft questions with your supervisor before committing.
If you are stuck between several ideas, our dissertation proposal writing support can help you test feasibility and sharpen a topic before you commit months of research time to it.
