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.

Teaching activity
- Analysis and scientific computing for undergraduate engineering students at the ENPC (2020, 2021).
This course was taught in a flipped classroom, in French (2020) or English (2021). - Partial differential equations and finite element methods for undergraduate engineering students at the ENPC (2021).
I led weekly exercise sessions and classes for one group of students, in English.
