I am researcher and professor at the Ecole Nationale des Ponts et Chaussées - Institut Polytechnique de Paris (ENPC-IP Paris).
I am a member of the joint project-team Matherials between Ecole Nationale des Ponts et Chaussées and INRIA.
Here is my cv (pdf).
I spent the 2019-2020 academic year in the mathematics department of Imperial College of London, in the Abraham de Moivre International Researche Laboratory.
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 (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).
