I am a researcher in applied mathematics and computer science working for CNRS at Ceremade, Université Paris-Dauphine. Before this, I was in Laboratoire Jean Kuntzmann in Grenoble.

Research topics: Computational geometry, geometric inference, computational optimal transport. More generally, I'm interested in the discretization of geometric variational and inverse problems.
