I am research scientist of the French National center for Research (CNRS), at IPAG (Grenoble planetology astrophysics laoratory), and previously at LAT (Toulouse Astrophysics Laboratory). I am also member of the INRIA STEEP team. In the last few years, my research activity has been mostly devoted to sustainability science. However I still have a theoretical activity in in dynamical planetology.

On the dynamics side, my work focuses on the coupled dynamics of planetary rings and planetary satellites. In the past, I have been working on hydrodynamic and MHD turbulence in accretion discs. The recent aspects of my research activity are described in the Dynamics section.

Since 2005, I have been spending an increasing fraction of my time on environmental issues and their relations to human development, both in terms of outreach and research. This now constitues the core of my research activity, which bears on the question of sustainability of coupled social-ecological systems at the local to regional scales. This aspect of my activity is described in the Sustainability section.
