Scientific activities

My main interest concerns the understanding of regional marine systems, based on the development and use of regional ocean hydrodynamic models, coupled with biogeochemical, atmospheric and sediment transport models, and used jointly with in-situ and satellite observations. My research activity mainly focuses on :

– the physical processes involved in the functioning of ocean dynamics in regional marine systems,

– the response of dynamics to different factors of variability at all scales,

– the influence of dynamics on the cycle of matter.

My two main areas of study are the Mediterranean Sea and the Southeast Asian Sea, with a focus on coastal areas from the Gulf of Tonkin to the Gulf of Thailand.
