About me


I am a Postdoctoral researcher in applied mathematics for the numerical simulation of complex physic problems.

As a computational scientist I have a strong background in numerical methods with skills in numerical analysis for PDEs and strong programming skills (Fortran/C++/Python/Matlab) and physics (fluid and solid mechanics, geophysics or biology). I am also interested in the optimization and the portability of the numerical methods on high performance computing architectures (HPC).

More specifically, my thesis focused on the use of non conforming hybrid high-order finite element methods (HDG/HHO) especially in the context of unfitted methods. These latter allow the boundary or physical interfaces to cut arbitrarily through the mesh cells.

Research interests


  • Numerical methods:
  •        -    Finite Element Methods (FEM)
           -    High-order nonconforming polytopal methods (HHO - HDG - dG)
           -    Unfitted methods (also known as embedded or immersed methods)

  • Application domains:
  •        -    Geophysics (wave propagation - climate modeling)
           -    Solid and Fluid Mechanics
           -    Biology
