I am interested in the physical processes at work in natural flows with complex rheology (landslides, avalanches, glaciers, etc.) on Earth and on other planets. My ambition is to advance both our understanding and the modeling of these processes. My work combines theoretical and numerical approaches as well as laboratory and field experiments. Recently I have focused on the interactions of these processes with the solid earth and the ocean by studying the seismic and water waves generated by landslides and glaciers. I enjoy working on the many exciting applications of this research in fields such as hazard assessment and the study of volcanic activity through gravitational flow monitoring, carried out in conjunction with volcano observatories.
