I am a last-year Ph.D. student at Inria, in the Mind team (formerly Parietal). I work with Aapo Hyvärinen and Alexandre Gramfort on statistical estimation of energy-based models.

I hold a master’s degree in applied mathematics and engineering from ENSTA Paris, and a master’s degree in machine learning from ENS Paris-Saclay.
