About

I am currently doing a postdoc in MPI-SWS, Kaiserslautern, with Georg Zetzsche, in the Models of Computation group. Before that, I completed a PhD in LaBRI, Bordeaux, under the supervision of Anca Muscholl and Igor Walukiewicz. My thesis is about verification and control problems over models of distributed systems, but I am interested in everything related to automata, logics and games. Before that, from 2017 to 2021, I was a student at the ENS Paris-Saclay.
