Born in 1960 in Saint-Etienne, France, he graduated from Ecole Polytechnique in 1983, he obtained his PhD in Chemical Engineering at Mines ParisTech in 1990. In 2000, he obtained his "habilitation à diriger des recherches' in Mathematics at University Paris-Sud Orsay.From 1993 to 2005, he was an associated professor at Ecole Polytechnique in Applied Mathematics. From 1998 to 2002, he was the head of the Centre Automatique et Systèmes of Mines ParisTech. He is now "ingénieur général des mines" and professor at Mines ParisTech. His fields of interest include nonlinear control and system theory with its applications. His contributions include differential flatness and its extension to infinite dimensional systems, nonlinear observers and symmetries, process control, motion planing and tracking for mechanical systems, feedback stabilization and estimation for electrical drives, internal combustion engines and quantum systems.In 2011, he contributed to the first experimental realization of a quantum feedback loop performed by the group of Serge Haroche at Ecole Normale Supérieure de Paris, an experiment which is referred to in the Scientific Background of the Nobel Prize shared by Haroche and David Wineland in 2012.He is a member of Quantic, a project team on quantum engineering including three PSL Research University members: Inria, Ecole normale supérieure, and Mines ParisTech, plus UMPC and CNRS.
