About me

Positions

During this academic year, from 2024/09/01 to 2025/08/31, I am part-time in Delegation to CNRS.

Since 2012/09/01, I have been an assistant professor (maître de conférences) at Sorbonne Université in the PolSys team of LIP6. I have defended my habilitation (HDR) on 2023/09/21.

From 2011/09/01 to 2012/08/31, I was a temporary researcher and teaching assistant in the Laboratoire de Mathématiques de Versailles (LMV).

From 2008/10/01 to 2011/12/06, I was a Ph.D. student in the Laboratoire d'Informatique de l'École polytechnique (LIX) under the guidance of Marc Giusti and Grégoire Lecerf.
