I am a 2nd year PhD student in the MATHERIALS team at CERMICS/INRIA under the supervision of Claude Le Bris, Alexei Lozinski and Frédéric Legoll.

PhD topic: “Difficult” multi-scale problems and non-intrusive methods.
During my PhD project, I will be looking into numerical methods of MsFEM type, in particular for multi-scale non-self-adjoint problems such as the advection-diffusion equation. Ways to make these methods as little intrusive as possible will also be considered.
