Research

My current research interests focus on the numerical modelling of nonlinear gravity waves in oceans and wave tanks. I work on the development of efficient numerical models in this concern and especially with pseudo-spectral methods (High-Order Spectral approach). Using those models, I am interested in the understanding of nonlinear processes during wave generation and propagation (instabilities, freak waves…). The inclusion of additional physical processes in nonlinear wave models is now my primary concern: variable bathymetry, wind forcing, whitecapping dissipation…

In addition, I work in close collaboration with other members of LHEEA Lab. for wave-structure interactions and the set-up of efficient coupling strategies: RANS solvers with SWENS approach or SPH method.

My research activities lead me to take part to different collaborations and research projects. For instance:
  • IRT Jules Verne: SimAvHy and HySMar research projects
  • ANR projects (Monacorev, Turbulon, …)
  • …
