The Application Form
Most sections are straightforward and easy to complete however below we have guidance on the sections which sometimes lead to questions.
Statement of Interest
The information you provide in the 'Statement of Interest' section should enable the Postgraduate Admissions Committee to understand your motivation for choosing your research interests. In addition to this motivation statement, please include as much information as possible about the type of work (e.g., observation-based, data-science/statistical analysis, computer simulations, theory) you plan for your PhD thesis.
Funding Your Study
Please read our funding section carefully paying particular attention to the section which relates to your current fee status.
What is a Cambridge College and how to choose one
When you join the University, you become a member of a College. Your College is separate to your academic department.
In your application, you'll be asked if you want to select up to 2 College preferences. If you don't have a preference, we will allocate one for you.
Colleges are friendly and supportive communities of academics and students from a mix of subjects.
There are 31 Colleges in total, each with its own facilities and traditions.
Colleges are an important part of the Cambridge student experience, so make sure you take the time to research them before you apply.
You can't transfer to another College once you've been offered membership, unless it's to take up a major funding offer from a different College.
Please visit this page on Cambridge Colleges for more information.
What happens next?
You can track the progress of your application on the Applicant Portal. The selection of applicants eligible for STFC Studentships will take place in early February. If you are shortlisted and live in the UK, you will be invited to visit the Institute for an interview during February 2026. After the interviews, provisional awards will be offered to the highest-ranked candidates.
For applicants seeking non-STFC funded places, the initial assessment will be based on your academic record and the availability of suitable projects and supervisors. If you are shortlisted for a PhD place, you will be interviewed via Zoom, these interviews are likely to take place in January.
Many applicants apply to several universities, each with different admission timelines. If you receive an offer from another university but are still interested in a PhD at the Institute, please contact Admissions before responding to the other offer.
