Short bio
Since January 2024, I hold a permanent research position (CNRS) at LIS in Marseille, in the MOVE team. From January 2022 to December 2023, I was a postdoc under Michał Pilipczuk at MIMUW, University of Warsaw. From September 2018 to October 2021, I was a PhD student at IRIF in Paris, under the supervision of Nathanaël Fijalkow and Olivier Serre. Before that, I studied theoretical computer science and mathematics at École Normale Supérieure de Lyon.
Research
My current research involves structural and algorithmic aspects of infinite duration games, as well as different problems related to logics on graphs. In the past, I have also worked on verification, arithmetic circuits, stochastic control, and a bit of AI.
