My research focuses on seabird spatial ecology, on topics dealing with behavioural ecology, life-history and population dynamics. I address a range of questions from understanding the drivers of migration and the consequences of migratory strategies on individual fitness and population dynamics, to investigating foraging niche differentiation in sympatric species, or the mechanisms of carry-over effects in migratory species. To address these questions, I use a combination of tracking loggers, video cameras, field experiments, and machine-learning analytical techniques. I work with mutliple seabird species across the North Atlantic, Indian and Pacific Oceans. At NINA, I co-lead SEAPOP fieldwork on the Røst archipelago (Northern Norway).
