Profile
My research focuses on combining satellite tracking with multi-scale environmental data to investigate the movement ecology of sea turtles in the western Indian Ocean.
Working closely with a team led by Prof. Graeme Hays and Dr Nicole Esteban our research is revealing the importance of the Chagos Archipelago to the greater WIO environment through identification of migratory routes and key foraging areas of both adult and juvenile green and hawksbill sea turtles.
High accuracy satellite tracking is showing that for some large marine vertebrates, even small protected areas of only a few km2 can encompass the movements of a large proportion of individuals over long periods.
