Our Researchers

Dr. Maxime Geoffroy
Research Scientist
(709) 778-0652
Research Areas:
Bioacoustics, Northward Range Expansion of Boreal Fish Species, North Atlantic and Arctic Pelagic Ecosystems

Dr. Maxime Geoffroy is a research scientist with expertise in bioacoustics, marine ecology and biological oceanography. His research aims at better understanding the ecology of North Atlantic and Arctic pelagic fish in relation to hydrography and climate change. In addition to ship-based surveys, he uses new technology, unmanned vehicles and active acoustic moorings, to study marine ecosystems.

Prior to working at CFER, Maxime was a postdoctoral researcher at the Department of Arctic and Marine Biology of UiT the Arctic University of Norway. He holds a Ph.D. in oceanography and an MSc in biology from Laval University, and a degree in mechanical engineering from the University of Ottawa.

Dr. Geoffroy is currently supervising students in the MSc and PhD program. To inquire on future opportunities, you may contact Dr. Geoffroy directly.
