Area of Expertise:

Francis Juanes is the Liber Ero Chair for Fisheries Research and a Professor at the University of Victoria. Francis works mainly on the behaviour, ecology and evolution of fishes and marine invertebrates. Francis did his undergraduate degree at McGill, M.Sc in Biology at Simon Fraser University and PhD in Coastal Oceanography at the State University of New York – Stony Brook. After a post-doctoral position in fisheries oceanography at UBC, Francis became a professor at the University of Massachusetts, Amherst, where he taught for 18 years until relocating to UVic in 2011. He has mentored many graduate students and postdocs in a variety of research areas. He is an editor of the ICES Journal of Marine Sciences and the Book Review Editor for the American Fisheries Society. Currently, Francis’ work focuses on the effects of anthropogenic noise on fish behavior and physiology; measuring and describing underwater soundscapes in a variety of freshwater and marine habitats; predator-prey interactions in piscivorous fishes; coastal marine biodiversity; and early life history of Pacific salmon.
