Scientist
After obtaining a doctorate from the University of Poitiers on the laser shock adhesion testing (LASAT) process in 2004, I continued my research on shock waves by joining CEA Valduc for two years of post-doctoral work on the equation of state and spalling of a lead-calcium alloy. During those two years, I had the opportunity to carry out the entire range of studies on this material: realization of plate impact experiments, simulation and modelization of the material. In 2007, I joined CEA DAM Île-de-France to continue my studies on the modeling of metallic materials under shocks, particularly the mechanical aspects: material failure (spalling, fragmentation), dynamic friction, and behavior laws. In this context, I am called upon to propose experimental concepts such as the development of plastic instabilities in detonation conditions and then to interpret these experiments in order to propose a model that can be used in hydrodynamic codes. Together with my colleagues, we have developed techniques and codes using, among other things, Bayesian inference to link the experimental results and the modeling. I am also actively involved in various scientific communities (LRC FragDyn, Chocodyn Research Federation, DYMAT), whether through scientific collaborations, presenting courses on the modeling of metallic materials under shock, or organizing thematic schools and symposiums.
