 The marine environment is wide and highly dynamic at various spatial scales. It is the home for numerous sub aquatic animals and plants, but also for various air-breathing animals, most of them being top predators. These air-breathing vertebrates face a number of particular challenges specific to the marine environment including living in the cold, feeding where they cannot breathe, finding dynamic food resources... These constraints led to remarkable morphological, physiological and behavioral adaptations. My research activity mainly focuses on behavioral adaptations of seabirds and marine mammals, with special emphasis on movement and diving behavior in relation to the marine environment, and behavioral plasticity. This kind of information is now mostly acquired through emitting and/or recording telemetry, including a variety of electronic devices. I have worked in a variety of marine ecosystems, including High Arctic (Spitzbergen), low Arctic (Northern Norway, Hornoya Isl.), coastal temperate West Atlantic coast ( France ), Tropical Pacific ( Hawaii , Tern Isl.), Subtropical Southern Indian Ocean (Over wintering 16 months at Amsterdam Isl., French Territory, Kangaroo Island- Australia), Sub Antarctic Southern Indian Ocean (Kerguelen and Crozet Archipelagoes, French Territories), . and on a variety of marine predators, including penguins, albatrosses, cormorants, murres, kittiwakes, fur seals, sea lions and elephant seals. After working and doing my PhD at the Centre d'Etude Biologiques de Chize (CNRS) in France for 6-7 years, I'm currently doing a post doc as part of the TOPP (Tagging Of Pacific Pelagics) program. I'm running deployment tests and calibration of new generations of electronic tags, on pacific albatrosses and Northern elephant seals mainly. I am also developing analytical tools (the IKNOS toolbox), for tracking and diving data analysis.
