Short bio

I am an associate professor (maître de conférences) at the Aix-Marseille University, member of the ACRO team, part of the LIS laboratory. Prior to that I spent one year as a postdoc at University of Warsaw. I defended my Ph.D. at Université Clermont Auvergne. My research focuses on algorithms and combinatorics mainly in graphs, hypergraphs, lattice structures, and Boolean logic.

I am in charge of the ACRO seminar since January 2023: please contact me if you want to come to Marseille and give a talk!

Keywords
