Research

I am physical researcher focusing on the physical variability of the tropical ocean and its role in the climate system. I am more specialized on upper ocean variability from diurnal to interannual timescales based on observations and modelling tools. I am fully involved in ocean observations (PIRATA program), from data collection to its integration into models using assimilation methods.
