Presentation

I am a mathematician. My research is mostly devoted to the modelling and asymptotic study of various physical problems. A significant part of my work deals with phenomenons arising in oceanography.

My main expertise area is showcased in the memoir Many Models for Water Waves. Here is a resume.
