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).
