Post-doc at Laboratoire Jacques-Louis Lions of Sorbonne University.
I am currently a post-doc researcher at Laboratoire Jacques-Louis Lions, working in scientific computing in applied mathematics, with Professor Bruno Després. In particular I'm interested in kinetic equations, the Vlasov-Poisson system, the Fokker-Planck-Landau equation as well as their applications to plasma physics.
I completed my PhD at UCLouvain in Belgium under the supervision of Jean-Francois Remacle and Christophe Geuzaine, as a member in the HEXTREME team.
