Parcours de recherche

Après une thèse et un post-doctorat dans le domaine des atomes froids et de la condensation de Bose-Einstein, j’ai été recruté en 2004 comme chargé de recherche au CNRS, dans le Département d’Optique ultrarapide et Nanophotonique (DON) de l’IPCMS. Depuis, j’étudie la photoréactivité de molécules organiques en phase condensée, par spectroscopie UV-Vis femtoseconde, dans l’équipe « BIODYN », que je dirige depuis 2016. Promu Directeur de Recherche en 2019.
