I am a postdoctoral researcher at the Software Languages Lab at the Vrije Universiteit Brussel, Belgium, under the supervision of Dominique Devriese. I previously worked at KU Leuven, where I obtained my PhD in August 2020.

Most of my research is about dependent type theory, where I am interested in the theory and implementation of modal and presheaf type theory (particularly directed type theory), as well as side-effects. I am also involved in a line of research, headed by Stelios Tsampas, on categorifying secure compilation.
