*Update: I'm now a Minerva postdoc fellow hosted by Liron Cohen at Ben-Gurion University, a new website is under construction and will be linked from here shortly.*

Hi, I'm Dominik and I was a PhD student at the Saarbrücken Graduate School of Computer Science and the Programming Systems Lab.

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 mechanised first-order logic and categorical axiomatisations of second-order ZF, both using the Coq proof assistant.
