Biography
Born in Winnipeg, Manitoba, Collie studied Biology at the University of York in England, where he became interested in quantitative ecology. His Ph.D. in Biological Oceanography from the MIT-WHOI Joint Program combined his interests in benthic ecology with fish population dynamics. Collie worked for three years at the University of British Columbia and four years at the University of Alaska, before joining the faculty of the Graduate School of Oceanography.
Research
I am a quantitative marine ecologist who concentrates on exploited marine fish and invertebrate populations. Obtaining unbiased estimates of animal abundance is the first step in the study of fish population dynamics. I supervise the GSO Fish Trawl Survey, one of the longest continuous records of fish and invertebrate abundance in the world.
My research focuses on the factors affecting the productivity of marine fish populations: harvesting, climatic variability, trophic interactions and other human disturbance. I fit population models to determine reference levels for overfishing and targets for sustainable fisheries. We are investigating how climate influences the productivity of marine fish stocks and designing harvest policies to react to these climate-induced changes.
Food-habits studies have been an on-going focus of my lab. Diet data form the basis of a suite of multispecies models, including energy budgets, biomass-dynamics, length-based, and age structured multispecies models. A statistical age-structured multispecies model is being used to inform biological reference points for a set of species in the mid-Atlantic.
Human impacts on benthic habitats, such as off-shore energy development, is another of my ongoing research interests. A 15-year field study s on the impacts of bottom fishing on the benthic communities of Georges Bank, is contributing to meta-analyses of the impacts of bottom fishing in 24 regions around the world.
