Présentation

Research fields

My research is devoted to dynamical gravitating systems : celestial mechanics, self gravitating systems (globular clusters & galaxies)[details in french], cosmological dynamics [details in french]

Teaching

I'm professor at Ensta ParisTech Paris-Saclay University in the domain of theoretical physics, astrophysics and modelisation [L3,M1, M2]

Scientific mediation

I give a lot of conferences [see the program since 2011], I'm in the scientific organising board of the "Festival d'astronomie de Fleurance", I propose also various activities for teachers : Eratothenes experiment, activities related to the moon, Hubble law reconstruction, etc. [details in french].

I have proposed a serie of 3 episodes for understanding the expansion of the univers and relativity theories

I have produced with Arthur Pesah a website to understand the spiral structure of galaxies : the spiral Kreator
