I am a researcher in applied mathematics. My main interests are the analysis and the design of numerical methods for fully nonlinear elliptic equations, such as Hamilton–Jacobi–Bellman equations from optimal control, and Monge–Ampère equations arising in optimal transport.

I work at CEREMADE, the department of mathematics at Université Paris Dauphine, where I have a position as a maître de conférences (approximately equivalent to associate professor).
