Modules

Audited modules in our International PhD Academy

The structure of Year 1 of your PhD can be tailored to your previous research experience.

You’ll be embedded in the laboratory of your supervisor and start your research project. If you need extra training to support your progress, subject-specific taught modules are available. You’ll audit these modules, which means you take part in the teaching and learning activities but don’t submit any assessments for credit. This extra training will give you the skills and confidence to excel in your PhD research, and open a wealth of career opportunities.

Audited modules are aimed to improve your:

practical experimental skills
analysis skills
academic writing skills.

Find our more about our audited modules

We regularly review our modules to incorporate student feedback, staff expertise, as well as the latest research and teaching methodology. We’re planning to run these modules in the academic year 2024/25. However, there may be changes to these modules in response to feedback, staff availability, student demand or updates to our curriculum. We’ll make sure to let you know of any material changes to modules at the earliest opportunity.

How to apply

If you’d like to join us as a research student, there are three main routes:

browse funded projects in this subject area
browse our potential supervisors and propose your own research project
browse available PhD projects in the International PhD Academy if you’re a self-funded or sponsored international student applying to the International PhD Academy.

Find out how to apply for a PhD at Sussex

If you choose to apply to the International PhD Academy, please:

include information on your experience, motivation and interests in your personal research statement
add the title and name of two supervisors of projects
label your supporting documents clearly with International PhD Academy in the title.

Full-time and part-time study

Choose to work on your research full time or part time, to fit around your work and personal life. For details about part-time study, contact us at lifesci-REC@sussex.ac.uk

PhD or MPhil?

You can choose to study for a PhD or an MPhil. PhD and MPhil degrees differ in duration and in the extent of your research work.

For a PhD, your research work makes a substantial original contribution to knowledge or understanding in your chosen field.
For an MPhil, your work is an independent piece of research but in less depth than for a PhD. You’ll graduate with the degree title Master of Philosophy. You might be able to change to a PhD while you study for an MPhil.
