To begin the application process, fill out the pre-application form to receive the application materials. The application deadline is December 31, 2023.

After you fill out your pre-application, you will receive an email with further instructions. This email will include:

  1. The application form.
  2. A reference form which you should send to a person who is willing to write a letter of reference on your behalf.
The letter of reference should confirm any of the following: your background, the ACT School's relevance to your research or career, or your research or career experience.

If you have any questions, contact the organizers of the Adjoint School by emailing

A reminder for non-UK applicants: Please check whether you need a visa to attend the research week. Keep in mind that processing times for visa applications may be long, so it may be necessary to start the process early to ensure that you can travel to the UK for the research week.

Who should apply?

Anyone, from anywhere in the world, who is interested in applying category-theoretic methods to problems outside of pure mathematics. This is emphatically not restricted to math students, but one should be comfortable working with mathematics. Knowledge of basic category-theoretic language—the definition of monoidal category for example—is encouraged.

We will consider advanced undergraduates, PhD students, post-docs, as well as people working outside of academia. Members of groups which are underrepresented in the mathematics and computer science communities are especially encouraged to apply.
