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**.
