My research focuses on the study of gravity instability processes (debris avalanches, landslides, debris/mud flows, etc.) that occur in subduction zones, both on the seafloor and on volcanic islands. I combine and analyse geological data, geophysical measurements and field observations to characterise and map these instability processes, on both small and very large scales. By interpreting the data, I can develop a depositional model and carry out palaeo-reconstructions in sedimentary basins. The main aim of my research is to gain a better understanding of the triggering mechanisms (volcanic eruption, dissociation of gas hydrates, tectonic activity) and the dynamics of these mass movements in order to assess the risks associated with them. My research endeavours to diversify the areas and factors of gravity instabilities studied and more recently, aims to develop the submarine palaeoseismological approach.

I'm also experienced with oceanographic expeditions with the International Ocean Discovery Program (IODP). I've participated to three expeditions offshore New Zealand and Japan onboard the research vessels Joides Resolution and Chikyu. I've also embarked the RRS Discovery offshore Nova Scotia.
