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
Computational 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.
Computation of electromagnetic fields in a cavity, or near an obstacle, with a non-smooth boundary. When the computational domain is non-convex, the presence of reentrant edges and/or vertices, called geometrical singularities, produces intense fields. Numerically, it can be interesting to use an ad hoc discretization method, such as the singular complement method (SCM), the Fourier singular complement method (FSCM), or the weighted regularization method (WRM). I also study "classical" numerical schemes, based on edge finite elements, and more recently on Staggered Discontinuous Galerkin techniques.
External collaborations: domain decomposition methods to solve the neutron diffusion equation in realistic configurations (Coll. CEA/Saclay) ; revisiting finite elements (Univ. Zürich).

PhD proposal Nonlocal models for interface problems between dielectrics and metamaterials in electromagnetism.

Postdoc proposal Computational homogenization for multi-group diffusion problems in neutronics.
