The world is changing at unprecedented rate. Climate is changing and shifting, landscapes are being profoundly modified by human activities. I am an empirical population geneticist amd my research aims to understand how these factors affect population dynamics and demography in natural systems, with a particular focus and rapidly changing ecosystems, i.e., Arctic and Alpine Biomes. The ultimate goal of my research is to inform on the consequences of on-going climate change on genetic diversity.
I conducted comprehensive circumpolar population genetic studies on caribou and previous works on ivory gull with a well established network of collaborators. I am Member of the Arctic Ecology Research Group (GREA, France) and Center for Northern Studies (University Laval, Canada).

I started in 2018 a new project supported by The French Polar Institute Paul-Émile Victor (IPEV) on Ivory Gull in North Greenland.
