Scientific Résumé

since 2013

Associate Professor at mathematic laboratory of Paris-Sud University

2011 - 2013

Postdoctoral research - LEGI/ LJK, Grenoble INP

ANR SCALE. Position at the laboratories LEGI (mecanics) and LJK (applied mathematics) in Grenoble, adviser : G.H. Cottet (LJK), G. Balarac (LEGI) et C. Picard (LJK). Subject : developp parallel implementation for particular method and coupling them with spectral schemes (or finite-volume schemes on unstructured mesh). The purpose is to simulate the advection of a (non-diffusive) scalar by a turbulent flow. Finer mesh are used to discretize the scalar and thus the cfl of classical scheme restrict too much the time step.

2008 - 2011

Phd thesis - University of Bordeaux, Institut de Mathématiques de Bordeaux/INRIA Bordeaux Sud-Ouest

Modeling tumor growth: Parameter estimation (recovery of the vasculature) and model devoted to gliomas (brain tumor) and numerical simulations of these models.

Advisors

Thierry Colin and Olivier Saut

Summer Programs
