About

I am a first-year PhD student at École Normale Supérieure – PSL in Paris, supervised by Giulio Biroli (ENS) and Marc Mézard (Bocconi University). I am based at the Centre de Sciences des Données and the Laboratoire de Physique de l’ENS (LPENS).

My research aims to build a theoretical understanding of diffusion models, currently the dominant approach to generative AI, using tools from statistical physics.
