I am a mathematician, working as a CNRS researcher at the Laboratoire de Mathématiques d'Orsay. My office is 2F1 (second floor of LMO).

My research interests are mostly in partial differential equations, spectral theory and machine learning. My CV is here.

News: From May 14 to June 4, 2025, I will give a Peccot course at the Collège de France on the stability of optimal transport. I will present the many theoretical advances recently made on this topic, combining partial differential equations, spectral theory, and functional inequalities. I will also explain the importance of this problem, both from a 'fundamental' perspective and a 'computational' one, since transport between measures plays a key role in many recent developments in imaging and machine learning.
