Présentation
I graduated from the Ecole Centrale de Paris in 1993, and the same year I obtained a Master M2 (laser and plasma) from the Université Paris-Saclay. Associate researcher at Centralesupelec, I have been pursuing research on the understanding of irradiation effects in solids since 1995 at CEA. In the framework of this research, I have developed a grazing incidence diffraction technique to measure the effect of irradiation by particle beams on materials (Rietveld analysis and setups), a method to simulate irradiation damage by ion beams and currently a phase field method to understand the impact of irradiation damage on materials (evolution of the microstructure, modification of properties). I lead a team of researchers both theoreticians and experimenters to use irradiation to produce materials with tunable properties. I develop and handle non-equilibrium statistical physics concepts and very powerful measurement techniques (High Resolution Diffraction, Atom Probe Tomography). The key point of my research team is to combine theoretical developments, numerical simulations and very high precision measurements to better understand and model the behavior and properties of materials subjected to harsh environments.
