Since September 2022, I have been a PhD student under the supervision of Julien Reygner (CERMICS, École Nationale des Ponts et Chaussées) and Philippe Moireau (Inria M3DISIM, École Polytechnique). I also have a temporary teaching position (« caïman ») at École Normale Supérieure de Paris (ENS).

I am a member of the probability and statistics research team at Département de Mathématiques et Applications (ENS DMA).

Research interests

My research work is two-sided:

  • On a one hand, I am interested in propagation chaos and local equilibria for conditioned mean-field systems of interacting particles. Using large deviation and stochastic control tools, we study suitable extensions of the Gibbs principle (well-known in statistical physics), in collaboration with Giovanni Conforti (CMAP, École Polytechnique).

  • On the other hand, I am interested in the link between stochastic filtering and deterministic estimation for non-smooth dynamics. We also apply the above stochastic tools to muscle modeling, in collaboration with Matthieu Caruel (MSME, Université Paris-Est Créteil) and François Kimmig (Inria M3DISIM).

More globally, I am interested in the links between non-equilibrium statistical physics and stochastic estimation, through the powerful notion of entropy.
