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.
News
- The paper was featured by LPENS, CNRS INSU, and IAS Paris-Saclay.
- Our paper Why Diffusion Models Don’t Memorize received an Oral and a Best Paper Award at NeurIPS 2025.
- Started my PhD at ENS–PSL with Giulio Biroli and Marc Mézard.
