Tuna behavior and ecology: tropical tuna fisheries in the Indian Ocean, their impacts on the high seas ecosystems and how they interplay with the physical and biogeochemical environment. These various interactions are used to develop an ecosystem approach to tuna fisheries.

Mesoscale studies (study area: Mozambique Channel): how mesoscale eddies and turbulence affect the distribution of phytoplankton and marine top predators (tuna, seabirds), and its role in the connectivity between distant ecosystems. This research work is based on shipborne observations (including physical oceanography, experimental fishing and electronic tagging of tuna and billfish), satellite data (SST, sea colour, altimetry) and ocean/ecosystem models products.

Impacts of climate change on fisheries: studies undertaken in the Indian Ocean (Wiley and FAO book chapters)

Field work at sea (physical oceanography, zooplankton, trawl surveys, fish biology, fishing gears) 
Analysis of environmental data (remote sensing, ocean model outputs, observations)
Fish stock assessment
Tuna aerial surveys
