Research interests
Research topics : Morphodynamics of mixed-energy (tide, waves) coastal environments. Characterisation and analysis of the physical processes controlling theses coastal environments by means of field measurements and numerical modelling of waves, hydrodynamic circulation, sediment transport and morphological changes. Deconvolution of morphological changes resulting from a change in the forcing (climate, human activity) and auto-cyclic ones.

Example of correlation between wave climate and the North Atlantic Oscillation (NAO):
Exemple de corrélation entre le climat de houle et l'oscillation nord-Atlantique (NAO):
