About me

I am a second-year PhD student in the Sierra team at Inria and ENS Ulm, under the supervision of Francis Bach and Michael I. Jordan. My research focuses on decision-making in multi-agent environments, an area that lies at the intersection of machine learning, statistics, and game theory.

Before my PhD, I earned a Master’s degree in Mathematics, Vision, and Learning at ENS Paris-Saclay and a Cycle Ingénieur Polytechnicien (X2020) degree from École polytechnique, where I majored in Applied Mathematics with an additional focus on Mathematics and Computer Science. I also worked on representation theory during a research visit to the Kyoto University Institute for Advanced Study.
