Physical oceanographer, Doctor de la Universidad de Toulouse Paul Sabatier, his research areas include tropical climate variability, ocean and climate, climate change, air-sea interaction, multi-model analysis, regional biogeochemical coupled model development. Over the past 20 years, he has been involved in various projects dedicated to the study of the South Eastern Pacific, dealing with regional air-sea interactions and the physical forcing of Oxygen Minimum Zone. He will supervise the Argo float deployments during the cruise and will coordinate the modeling work for the interpretation of the data collected during the cruise.
