Research interest:

My research is focused on understanding processes of water mass ventilation and ocean-atmosphere interactions within a very large range of temporal and spatial scales. I'm especially interested in the top layers of the ocean and their vertical structures, those under direct influence of the atmospheric forcing (and of the climate change ...). 

I explored the atmospheric part of air-sea interactions during my PhD (LPO, Brest and LMD, Paris, 2006). I studied coupled/forced interannual variabilities in the Southern Hemisphere with a numerical model of intermediate complexity I partially developed for this purpose.

I started my postdoctoral research at MIT in the Earth, Atmospheric and Planetary Sciences department (2006-2008). I focused on the ocean side of air-sea interactions. I studied subtropical mode waters formation processes and the impact of meso-scale turbulence on lateral heat fluxes using both observations and numerical simulations.

I continued my postdoctoral research at IUEM and Ifremer where I keep working on surface ventilation processes, although I extended my research area to the North Atlantic subpolar gyre. I try to improve the use of the oxygen variable to study the dynamic of subpolar mode waters, especially their ventilation and circulation.

Now only at Ifremer, still as a postdoc, as a research scientist, I use Argo data to caracterize the North Atlantic thermocline and its variability; a process tightly linked to the atmospheric forcing and the subtropical mode water cycles.
