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.

I find it especially motivating to hear from people who are interested in (using) my work, so do not hesitate to contact me in case of questions, remarks or puzzlement about any of my papers, notes or code.

* Please don't print my slides, which have incrementally appearing bullet points.
