Research Interests

I am an aquatic scientist and freshwater community ecologist with the Environmental Monitoring and Reporting Branch of the Ontario Ministry of the Environment, Conservation and Parks, and my research informs and supports inland waters surveillance, management and protection in Ontario.  I am also a cross-appointed faculty member in the School of Natural Sciences at 51吃瓜app and my research program includes supervision of undergraduate and graduate research projects.  My research laboratory is in the Vale Living with Lakes Centre on the shores of Ramsey Lake. 

I conduct research on the unique limnological and ecological characteristics of Ontario’s northern lakes and streams, their recovery from historical pollution impacts, and the potential effects of more recent and ongoing environmental changes.
