About me ...


My research focuses on the physics of Earth surface processes and how they impact the shape and dynamics of landscapes. I investigate these processes using laboratory experiments, mathematical modeling and field observations with the goal to identify the minimum number of ingredients necessary to model them. I am particularly interested in the extent to which small scale physics may control the evolution of large scale features of the Earth surface.


I also supervise the «Observatoire de l’Eau et de l’Erosion aux Antilles (ObsERA). This observatory, located on Basse-Terre Island, Guadeloupe archipelago, in the lesser Antilles arc, consists of several experimental watershed instrumented to investigate the dynamics of erosion and weathering.
