Academic interests

I joined the CEES as a post-doctoral fellow in October 2016 to work on the “Climate effects on harvested large mammal populations” project in close collaboration with the “DeerUnit” project. My main objective is to use GPS and activity data to answer fundamental question in deer ecology and more specifically what trigger migration and dispersal behaviour.

After a Master of Science in ecology at the University of Toulouse (France) working on the wolf and fox impact on a two ungulates system in north Apennine (Toscana, Italia), I completed my Ph.D. in the laboratory of Wildlife Behaviour and Ecology (Comportement et Ecologie de la Faune Sauvage CEFS-INRA) in Toulouse under the supervision of Dr Mark Hewison and Dr Richard Bon. My researches focused on the dispersal behaviour of a commonly distribute medium size ungulate, the roe deer. This study was individual-based, using the analyses of roe deer GPS locations and behavioural measurements, and aimed to reveal the importance of the inter-individual variation during the three phases of the dispersal process. After my Ph.D. I obtained a post-doctoral position for few months on the University of Lyon1 with Dr Jean-Michel Gaillard and Dr Cécile Vanpé where I studied the personality of roe deer using behavioural data recorded during capture in a Swedish population of wild roe deer. I continued my research as a post-doctoral fellow for two years at the population ecology lab of Dr Philip McLoughlin (University of Saskatchewan, Canada) where I worked on two study systems, the feral horse population of Sable Island and a threatened woodland caribou population in Northern Saskatchewan. My research focused on fundamental ecology and evolution using ungulates as model species, and more specifically, I was studying the social dispersal behaviour as well as the cost of reproduction on Sable Island horses and I also studied the movement patterns of caribou in Northern Saskatchewan.
