Antoine Van Muylder

I am a maths and computer science PhD student. I currently live in Brussels. You can email me at antvanmul then at then hotmail then .com. My office at KU Leuven is 200A (cs building), 03.127.

Research positions & studies

I am a PhD student working with Dominique Devriese and Andreas Nuyts at KU Leuven. My research is about parametricity for dependent type theories.

Before that, I was working as a research engineer at Inria Paris in the Prosecco team, where the F* Verification Language for Effectful Programs is/was being developed. I did my master internship with Catalin Hritcu in the same team (link).

I hold a bachelor's degree in mathematics from Université Libre de Bruxelles, and a master's degree in mathematical logic and theoretical computer science from Université de Paris.

Interests

I am interested in mathematical unifying theories for logic, computer science, algebra and geometry, as well as in those topics themselves. Here is a non-exhaustive list:

• Type theory, dependent type theory
• Parametricity
• Semantics for type theory
• Proof assistants
• Category theory
• Side effects in programs
