About Me

Hello there! My name is Lucien and welcome to my website. I completed my Ph.D. thesis at the end of 2019, afterward I worked as a postdoctoral researcher at the LMFA laboratory. I now continue my research as postdoctoral reasearcher at Centre Européen de Recherche et de Formation Avancée en Calcul Scientifique (CERFACS). My research interests include fluid dynamics, lattice Boltzmann method, multi-species diffusion, kinetic theory, and physical oceanography. You will find some posts about my research and links to my articles.

Besides my research, I can’t decide between the seaside and the mountainside enjoying windsurfing, sailing, as well as hiking, and mountain biking.
