Xavier VALENTIN
Xavier Valentin is a Research Engineer and holds a PhD in Applied Mathematics. He is currently a member of a R&D team at CEA whose objective is to develop new models and new numerical methods for HPC numerical simulation codes.
His main research theme is the analysis and the development of numerical methods for photons transport problems. In this context, he focuses on the deterministic methods (PN, SN) and on the probabilistic Monte-Carlo methods.
He regularly (co-)supervises internship on this theme.
