A strong Biomedical Science dissertation topic focuses on a single, current question in laboratory or clinical practice — such as antimicrobial resistance, molecular diagnostics, or AI-assisted reporting — that is narrow enough to research within UK NHS or university settings and supported by accessible literature and data.
Biomedical Science spans clinical biochemistry, microbiology, haematology, immunology, genomics, and cellular pathology, giving undergraduate and master’s students a broad field to explore. The themed lists below cover NHS-relevant and 2026 trending angles, each written as a ready-to-research working title.
If you are still narrowing your focus, our guide on how to choose a dissertation topic explains how to test an idea for feasibility first. You can also browse related lists such as our nursing dissertation topics and radiography dissertation topics for cross-disciplinary ideas.

How to Choose a Biomedical Science Dissertation Topic
Start by narrowing your interest to one discipline or specimen type — biochemistry, microbiology, haematology, immunology, genomics, or cellular pathology — rather than trying to cover biomedical science broadly in a single dissertation.
Check that UK data, NHS guidance, or published literature actually exists on your chosen angle before you commit, and confirm your university’s ethical and laboratory governance requirements if the topic involves patient samples, clinical data, or primary bench work.
Finally, discuss your shortlist with your supervisor early. A topic that sounds strong in theory can be difficult to research if sample access, ethics timelines, equipment, or word count constraints get in the way. For tailored guidance you can also speak to one of our biology and biomedical science writers.
