I am currently Chargé de recherche CNRS, at Institut de Recherche Mathématique, in Rennes, France (IRMAR).

My research is mostly devoted on the mathematical modeling and asymptotic study of various physical problems. An important part of my work deals with the modelization of phenomenons arising in oceanography, with a specific interest in the propagation of internal waves in stratified fluids. I also work on wave propagation in inhomogeneous media, and particularly in highly oscillatory microstructures. See this blog [»] for more details.

Virtuous advertising:
I cannot submit my work to this great new journal, but you should.


2008—2011: Ph.D. Thesis in Applied Mathematics, Ecole Normale Supérieure de Paris. The dissertation is available here
