 Quick Summary 

Since September 2021, I work as associate professor at Université Polytechnique Hauts-De-France (UPHF). Based on the campus Mont-Houy, I work in the department of Mathematics (CERAMATHS/DEMATHS) and teach at the INSA Hauts-de-France engineering school.

I was a research engineer at Inria in the team Makutu of Bordeaux research center. My work focused on the development of wave propagators in the multi-physics open source C++ code GEOS

From 2018 to 2020 I was Postdoctoral scholar at Stanford University working in the group SUPRI-b of professor Hamdi Tchelepi. My research work focused on the development of highly scalable algorithm and nonlinear preconditioner to solve multi-phase flow problems in porous media. This work is part of the FC-Maelstrom project effort to develop a massively parallel simulator for coupled flow and geomechanics in fractured and faulted reservoirs.  For more details, please refer to the preprint Comparison of nonlinear field-split preconditioners for two-phase flow in heterogeneous porous media.

My thesis develops a framework for the design of high order A-stable implicit, Optimized CFL number high order explicit and high order locally implicit time integration schemes for ODEs. I have implemented the developed schemes in the C++ code Montjoie and used them to solve the acoustic and Maxwell's equations. The time integrations schemes are coupled with high-order continuous and discontinuous finite elements for the spatial discretization like discontinuous Galerkine and hybridizable DG. I performed numerical simulations in 1D, 2D and 3D.
