Hugh MacIsaac

Job Title: Associate Professor
Employer: Great Lakes Institute for Environmental Research, University of Windsor
Place of Birth: Windsor, Ontario, Canada
Public School attended: Christ the King
High School attended: Vincent Massey
Further Education: University of Windsor (B.Sc.), University of Toronto (M.Sc.), Dartmouth College (Ph.D.).
Geographic focus of research: Great Lakes of North America, plus inland lakes in adjacent regions of Ontario, notably Muskoka.

Brief synopsis of current research:
We are working to identify 'corridors' of invasion to the Great Lakes from Eurasia. These corridors have resulted in large numbers of Ponto-Caspian and other Eurasian species entering the Great Lakes in secondary invastions. We are also examining invasion models to predict invasions of lakes in inland parts of Ontario from the Great Lakes by a variety of invertebrate species.

Canada is fortunate to have enormous quantities of freshwater. Study and management of our lakes is essential if future generations are to benefit to the extent that current Canadians have. Careers in aquatic science offer tremendous opportunity and responsibility for those of use fortunate to have selected a career in this field.
