I received a Bachelor's degree in marine biology from the University of Guelph, and a Ph.D. in limnology from the University of Manitoba, after which I conducted postdoctoral work at the NOAA Great Lakes Environmental Research Laboratory in Ann Arbor, Michigan. Most of my research is on large lakes, including the Laurentian Great Lakes, the African Great Lakes, and lakes in South America. Some of my specific interests include benthic carbon and nutrient dynamics, structure and function of aquatic food webs, and tropical limnology. However, I am generally interested in the interactions among physical, chemical and biological processes at the whole ecosystem scale, and so my research tends to be collaborative and multidisciplinary, with an emphasis on how land use, climate, and species composition affect ecosystem structure and function.
