Collecting larval lampreys

Research Interests

My primary research interests center around understanding fish population dynamics and applying quantitative tools such as simulation modeling and decision analysis to practical fishery management problems. My research has a strong applied flavor, and frequently involves working closely with fishery management agencies. I am especially interested in the challenge of determining critical uncertainties for fishery management, and the related question of assigning an appropriate value to reducing uncertainty. I like my research program, and thus my students' projects, to comprise a mixture of empirical and theoretical work: field and experimental studies; modeling and analysis.

Some of the problems that my students and I have tackled include:

sea lamprey control in the St. Marys River
evaluation and refinement of larval assessment methods for sea lamprey control
recruitment dynamics of sea lamrpeys and their implications for alternative control
energy dynamics of Great Lakes Chinook salmon
assessment of Lake Michigan salmonine stocking policies using decision analysis
development of efficient assessment methods for determining fish species composition of Great Lakes streams
habitat supply-population dynamics models for Lake Erie walleye, Lake Superior lake trout, and Lake Superior cisco
evaluation of harvest policies for Lake Erie walleye and Lake Michigan yellow perch using decision analysis
factors influencing differences in natural mortality rates among lake whitefish stocks
