Our research interests include:
- Category theory
- Higher category theory
- Topos theory
- Theory of (higher-type) computation
- Type theory
- Proof formalisation
- Proof theory
Every second Wednesday of the month, we get together for a Typical Lunch with people from the maths and CS departments that are interested in type theory and related subjects. If you are interested in joining these informal gatherings, please contact Johan or Paige for details about the exact time and location.

National seminars and workshops
Category theory seminar. The seminar runs every other week. Some of its topics include higher category theory, applications to homotopy theory and computer science.
Mathematical Logic Colloquium. Joint event organised by the mathematical logic departments in Amsterdam, Nijmegen and Utrecht. Currently dormant.
