Dr. Stéphane Gauthier is a research scientist with Fisheries and Oceans Canada. His main research focus is using acoustics (the transmission and interpretation of signals from scientific echosounders) to gain insight into ecosystem processes. Before joining Fisheries and Oceans Canada in 2011 he was a fisheries scientist with the National Institute of Water and Atmospheric research in New Zealand, where his work took him from the Arabian Sea to the Antarctic Ocean.

Stéphane holds a Ph.D. from Memorial University of Newfoundland, and did postdoctoral work at the University of Washington and Université de Montréal. For this scientific mission he is interested in the spatial variability of acoustic backscatter, and understanding how oceanographic conditions and pathways affect the distribution of pelagic organisms.
