I am a researcher in analysis interested in numerical analysis, geometric analysis and the calculus of variations. I study problems with free discontinuities, free boundaries or interfaces coming from applications such as image processing and reconstruction, physics and materials science. I am also interested in numerical optimization for non-smooth problems related to theses topics.
After having spent many years with CMAP, Ecole polytechnique, I am now a member of the applied maths department CEREMADE in Dauphine / PSL university.

Most of my publications is available and can be found on HAL (CVhal) or Google Scholar or MathSciNet. (Some old publications here.)
My recent work focus on some limiting energies for liquid crystals, the study of "GSBD" functions and the Griffith problem in fracture mechanics, on some interfacial evolution problems (anisotropic partitions, Wasserstein flow, crystalline curvature flow), on the discretization of the total variation and some techniques for differentiation in convex optimization.
