Dr. Patrick Bergeron is an assistant professor in the Department of Biological Sciences. He earned his Bachelor’s degree in Wildlife Biology at McGill and his PhD in Evolutionary Biology and Behavioral Ecology at the Université de Sherbrooke. He was also a postdoctoral fellow in population genetics at Dartmouth College (NH) and in biostatistics and epidemiology at the CRCHUS. He now collaborates with researchers in both the Département de Biologie and the Faculté de Médecine et des Sciences de la Santé at the Université de Sherbrooke. His main research themes focus on life-history trade-offs in the wild and epidemiology on big human datasets.
