50 Topic Ideas To Kickstart Your Research Project

Public health-related research topics and ideas

If you’re just starting out exploring public health and/or epidemiology-related topics for your dissertation, thesis or research project, you’ve come to the right place. In this post, we’ll help kickstart your research by providing a hearty list of research ideas, including examples from recent studies in public health and epidemiology.

PS – This is just the start…

We know it’s exciting to run through a list of research topics, but please keep in mind that this list is just a starting point. These topic ideas provided here are intentionally broad and generic, so keep in mind that you will need to develop them further. Nevertheless, they should inspire some ideas for your project.

To develop a suitable research topic, you’ll need to identify a clear and convincing research gap, and a viable plan to fill that gap. If this sounds foreign to you, check out our free research topic webinar that explores how to find and refine a high-quality research topic, from scratch. Alternatively, consider our 1-on-1 coaching service.

Recent Studies: Public Health & Epidemiology

While the ideas we’ve presented above are a decent starting point for finding a research topic, they are fairly generic and non-specific. So, it helps to look at actual studies in the public health and epidemiology space to see how this all comes together in practice.

Below, we’ve included a selection of recent studies to help refine your thinking. These are actual studies, so they can provide some useful insight as to what a research topic looks like in practice.

  • Tutorials in population neuroimaging: Using epidemiology in neuroimaging research (Godina et al., 2022)
  • Application of Big Data in Digital Epidemiology (Naaz & Siddiqui, 2022)
  • Response to comment on: Incidence of ocular and systemic disease affecting visual function among state bus drivers (Kohli et al., 2022)
  • Why epidemiology is incomplete without qualitative and mixed methods (Lane-Fall, 2023)
  • Teaching epidemiology: An overview of strategies and considerations (Hossain, 2022)
  • Social Epidemiology: Past, Present, and Future (Roux, 2022)
  • Population health assessment project: An innovative strategy for teaching principles of epidemiology (Keen et al., 2022)
  • The functions of veterinary epidemiology in public health (Shaffi, 2023)
  • Readying the Applied Epidemiology Workforce for Emerging Areas of
  • Public Health Practice (Daly et al., 2022)

  • Which disciplines form digital public health, and how do they relate to each other? (Pan, 2022)
  • Information Flow and Data Gaps in COVID-19 Recording and Reporting at National and Provincial Levels in Indonesia (Barsasella et al., 2022).

  • Sensitivity analysis of SEIR epidemic model of Covid 19 spread in Indonesia (Rangkuti et al., 2022)

As you can see, these research topics are a lot more focused than the generic topic ideas we presented earlier. So, for you to develop a high-quality research topic, you’ll need to get specific and laser-focused on a specific context with specific variables of interest.  In the video below, we explore some other important things you’ll need to consider when crafting your research topic.
