Hi, I'm Dominik and I'm a MSCA Postdoctoral Fellow hosted by Hugo Herbelin in the Picube Team part of IRIF and Inria Paris. Before that, I was a Minerva Postdoctoral Fellow hosted by Liron Cohen at Ben-Gurion University and a PhD student at the Saarbrücken Graduate School of Computer Science under the supervision of Gert Smolka.

I did my Bachelor's Thesis and a Research Immersion Lab on set theory mechanised in Coq. I obtained my Master's degree from the University of Oxford with a thesis on intersection type systems and nominal automata. I also completed a second Bachelor's degree in cultural studies with a thesis on foundations of mathematics, hosted by the philosophy department. In my PhD thesis I investigated various topics in metamathematics in constructive type theory and Coq.

I'm broadly interested in constructive and computational logic and its connections to the foundations and philosophy of mathematics. Currently, I'm mostly working on synthetic computability and constructive reverse mathematics, both using the Coq proof assistant.
