About me

Since October 2025, I am part of the Statistical Physics and Mathematics program as a post doctoral researcher at DMA (ENS, Paris). Before that I was at IMT (Toulouse) as a postdoc with Michel Pain, and I have completed my PhD thesis under the supervision of Alice Guionnet (ENS Lyon) in September 2023.

My research focuses on random matrix theory and its interactions with statistical physics and integrable systems ; more generally, I am interested in the study of random matrices through large deviations for the spectrum/the largest eigenvalue, fluctuations/local statistics of the spectrum.

You can find my CV here.
