About Me

I am a postdoctoral researcher at L2S, Université Paris-Saclay – CentraleSupélec. I work with Riccardo Bonalli and Laurent Pfeiffer on a project about risk-averse stochastic optimal control. Previously, I was a PhD student at IRMAR, Université de Rennes – INSA Rennes, under the supervision of Olivier Ley and Francisco Silva. I defended my thesis, entitled Contributions to the study of second order mean field games – approximation of stable solutions and sticky processes on networks, on October 23, 2025 at INSA Rennes.
