I am currently Research Professor (Directeur de Recherche) at the Centre National de la Recherche Scientifique (CNRS), at the Institut de Mathématiques de Marseille.

My main research interests are in nonlinear dynamics/dynamical systems with emphasis on Hamiltonian dynamics and chaos. I consider applications to atomic, molecular and plasma physics. 

Expert-evaluator for the European Commission, working for the European Research Executive Agency (in particular for Marie Sklodowska-Curie actions) and the European Education and Culture Executive Agency (in particular for Erasmus Mundus programs). 

Editor-In-Chief of Communications in Nonlinear Science and Numerical Simulation (Elsevier).
