About me
I am a Researcher at the Interdisciplinary Hub for Security, Privacy and Data
Governance (iHub) at Radboud University Nijmegen.
Here is a short overview of my CV
You can find my complete CV
here.
Research Interests
My main research interests are
 Category Theory
 Probability Theory
 Programming Language Semantics
These fields come together in exciting ways in
categorical probability theory and
probabilistic programming. Some of the mathematical tools I use are
Markov categories and
quasiBorel spaces.
Other
areas I'm interested in: functional programming with effects, type theory, (Bayesian) machine learning,
quantum computation, logic, topology and algebraic geometry.
