Frederic Guichard is a professor of biology at McGill University in Montreal, Canada. He received his PhD in marine ecology from Université Laval in 2000 and was a postdoctoral fellow at Princeton University prior to joining McGill in 2002, where he is co-director of the Center of Applied Mathematics in Bioscience and Medicine (CAMBAM) and co-founder of the PhD program in Quantitative Life Sciences. His research in theoretical ecology combines applied mathematics, computational tools and field experiments for the study of nonlinear dynamics and spatial structure in ecosystems. Prof. Guichard also applies his work to conservation and more specifically to the design of marine protected areas.Justin Marleau is a research associate in the Department of Biology at McGill University. While earning his PhD in mathematical and theoretical ecology at McGill in 2014, he became deeply interested in pedagogy, eventually becoming a biology college professor at Champlain Regional College in Saint-Lambert, Quebec from 2013–2016. After a brief sojourn in science policy with the Canadian federal government from 2016–2017, Dr. Marleau returned to full-time research at McGill, initially as a post-doctoral fellow. He specializes in the development of theory and models to advance our ability to predict and understand ecological systems.
