Dr Agnès Lewden

Research Fellow in Bird Flight Energetics
School of Biomedical Sciences

Background: I did my Masters at the University of Rimouski (Canada) in 2009. I studied the winter acclimatization in Black-capped chickadees (Poecile atricapillus L.) in free-living condition. I developed a keen interest for endotherm species living in cold conditions. Therefore, I have worked as a biologist for 15 months in the French scientific station "Dumont d’Urville" in Terre Adelie (Antarctica). Then, I completed my Ph.D degree under a three-year doctoral fellowship funded by the French Ministry of Education and Research studying the king penguin (Aptenodytes patagonicus) thermoregulation strategies and the energetic consequences.
