I am currently researcher at CERMICS and professor at the Ecole des Ponts ParisTech.

I am a member of the Molecular and Multiscale Modelling group at CERMICS and of the Matherials project-team at INRIA.

I am the coordinator of the ERC project MSMath.

Here is my cv (pdf).

I defended my habilitation thesis on 3rd June 2009 (abstract, manuscript). Title: Mathematical and numerical analysis of some models for materials, from the microscopic scale to the macroscopic scale.

During year 2004-2005, I had a post-doc position at the Centre de Recherches Mathématiques at the University of Montreal, in the context of a special year about the Mathematics of Stochastic and Multiscale Modeling.

I defended my PhD thesis on 21st June 2004 (abstract, manuscript). Title: Multiscale models for viscoelastic fluids. PhD supervisors: Benjamin Jourdain and Claude Le Bris.

Research interests

Micro-macro models for viscoelastic fluids (dumbbell model, CONNFFESSIT method, variance reduction methods, entropy estimates).
Free surface flow and magnetohydrodynamics. Application to the simulation of aluminium electrolysis cells (Arbitrary Lagrangian Eulerian method, moving contact line problem).
