I am an assistant professor in the Computer Science department at the École Polytechnique of the Institut Polytechnique de Paris.
My research is mainly on combinatorial optimization and graph algorithms.
I received my PhD degree from the École Normale Supérieure in Paris, under the supervision of Claire Mathieu.
Afterwards, I spent two years as a postdoctoral researcher at the MaxPlanckInstitut für Informatik in Germany.
Research internship position(s) on algorithms available for the season 20212022. Students with experiences on competitive programming are especially welcome to apply.
