Research:

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 and its variability. Mesoscale studies (Mozambique Channel), how mesoscale eddies affect the distribution of phytoplankton and marine top predators. This research work is based on at-sea measurements (including physical oceanography, experimental fishing and electronic tagging of tuna and billfish), satellite imagery (SST, sea colour, altimetry) and ocean and ecosystem models products.
