My scientific activity concerns the development of concepts and methods in relation with the dynamics of shallow water environments. I study the domain that extends from a few tens of meters of water depth at sea to the coastal watershed onshore, with a particular emphasis on the littoral area and the shoreline itself.
I have worked in Spain, Taiwan, Canada, Norway, Chad, Italy, Greece, Switzerland, USA, Tunisia, in the french Alps, in the Gulf of Lions (Mediterranean Sea) and in French Polynesia.
I build my research combining various points of view from applied mathematics to quantitative geomorphology, including physics, geophysics, civil engineering,some connections with coastal archeology, the analysis of littoral hazards, the quantification of littoral resources (such as sand stock, fresh water or Renewable Marine Energies).
From a strictly academic point of view, my activity focuses on: 1) the development of a non-linear diffusion formalism for beach morphodynamics, 2) the development of an alternative theory for beach morphodynamics by a minimization principle and 3) several developments in relation with air-wave-seabottom complex couplings in the nearshore.
