Extended CV

A brief curriculum
I got my PhD in 1992 in applied mathematics, and defended my 'Habilitation a Diriger les Recherches' in 1998 in mathematics. In both cases, I graduated from the Paris VI University.
Between Oct. 1990 and Sep. 1993, I studied parallel preconditioning within the Parallel Computing Project at the Limeil-Valenton Centre of the French Nuclear Agency (CEA). Starting in Oct. 1993, I spent one year as a post-doctoral fellow at UCLA, where I studied graph partitioning. Then, I spent three additional years at the Limeil-Valenton Centre: I worked on mesh partitioning and the parallelization of codes, and on the discretization of Maxwell's equations.
Since Sep. 1997, I have been working in the Applied Math Dept of ENSTA.

Research topics
Electromagnetics, numerical analysis of PDEs.

Propagation of fields at the interface between metals or meta-materials and classical dielectric media. In physics, these models allow one to take into account the onset and propagation of surface plasmons. With the help of the T-coercivity theory, one can solve those models mathematically and numerically when they are well-posed. One can also build configurations for which the problem is ill-posed. Current research focuses on the redefinition of the model in this case and on the design of adequate numerical methods. Numerical computations with the help of T-coercivity in various research fields: electromagnetics, neutron diffusion, incompressible fluids. External collaborations: domain decomposition methods  and a posteriori estimation to solve the neutron diffusion equation in realistic configurations (Coll. CEA/Saclay); discretization of Stokes and Navier-Stokes equations (Coll. CEA/Saclay); new discretization methods for elliptic problems (Coll. Univ. Zurich); interface models in electromagnetics (Coll. Univ. de la Republica, Uruguay).
