Background:

I recently retired after a 40-year career that included positions as a fishery science professor, researcher, manager, and consultant. I earned my PhD from Michigan State University, MS from Cornell University, and BS from the University of Wisconsin – Stevens Point.  My research focuses on fish population dynamics and modeling, with a dual emphasis on restoration of native lake trout populations in the Great Lakes region of North America and suppression of introduced lake trout populations in western North America.  I have authored more than 140 peer-reviewed articles, book chapters, and agency reports, and I recently co-edited a book on The Lake Charr Salvelinus namaycush biology, ecology, distribution, and management.  I also served for 13 years as a co-editor of the North American Journal of Fisheries Management.

Research:

• Life History Differentiation between Deep-Water and Shallow-Water Forms of Lake Trout in Large Lakes of North America
• Assessing Individual Variability in Growth Rates for Great Lakes Fish Populations
