Professor at the University of Quebec at Rimouski (UQAR), where I teach and direct a research program in animal ecology dealing with the management and conservation of terrestrial wildlife.

I hold a bachelor's degree in Wildlife Management (UQAR), a Master in Environmental Sciences (UQTR) and a Ph.D. in biology (UQAM), during which I examined the responses of birds and mammals to loss and fragmentation of the boreal forest. 

I then applied this research topic during a postdoctoral fellowship at UQAR. Currently I conduct research on the impacts of habitat alteration on the ecology of large mammals (woodland caribou, gray wolf, moose, coyote and black bear) using as primary tools spatial ecology, behavior, population dynamics and landscape ecology.


Research Themes

  • Animal ecology
  • Conservation
  • Terrestrial wildlife management
