ABOUT

I'm professor of mathematics and statistician at INSEE. From 2021 to 2024 I was a researcher at Inria, working with Sirocco / COMPACT team. In 2024-2025, I was a visiting researcher with the DECIDE Team, affiliated with Lab-STICC, CNRS UMR 6285, University of Bretagne Sud (UBS).

Since September 2025, I am a researcher and lecturer at the University of Rennes, Irisa laboratory, UMR 6074, in the DRUID team. I teach at ISTIC and am affiliated with the Tiare project.
