About Me

Hi, I am a Maitre de Conférence (Associate Professor) at the Institut de Mathématiques de Marseille and the Ecole Centrale de Marseille, since 2014. I am currently on research sabbatical at the Mathematics Department at the MIT.

Research Interest

My general interests lie in the interaction between statistics and geometry. More recently, I have been focusing my work on barycenters, and in the optimal transport in particular.
