2014-Current PhD in Computer Science at the University of Strasbourg
2009-2014 Mathematics teacher in high school


The main research topics for my thesis are: optimisation (loop optimisation, cache misses, communication-avoiding algorithms), parallelisation (MPI, OpenMP, vectorisation, scalability, MIC architectures), reproducibility, numerical simulations for plasma physics (two-species, Particle-in-Cell, Semi-Lagrangian).

My PhD advisors are Éric Violard, Michel Mehrenberger and Sever Hirstoaga.

My thesis is entitled "Parallelisation and optimisation of Semi-Lagrangian and particle methods for solving the Vlasov-Poisson system of equations".
