Dan (Daniel) Frumin
About me
I am a logician and a computer scientist in Fundamental Computing group at the University of Groningen. I am interested in concurrent programs and reasoning about their behavior. My research interest include
- semantics of programming languages;
- program verification and concurrent separation logics;
- substructural logics and their proof theory;
- type theory and type systems;
- formal proofs and proof assistants (especially Univalent Foundations).

Brief bio
I finished my PhD under the supervision of Herman Geuvers, Freek Wiedijk, and Robbert Krebbers at Radboud University Nijmegen. My thesis is available online, together with the associated Coq mechanizations. After my PhD, I have been a postdoc with Lars Birkedal at the Logic and Semantics group, and a postdoc with Jorge Pérez at the Fundamental Computing group.
