My work focuses on the ecology of fish communities in the Great Lakes, particularly in Lake Huron. I conduct work on the ecology and dynamics of the deepwater demersal fish community in Lake Huron, and also lake trout ecology. I have been involved in research on thiamine deficiency in lake trout, and also on botulism in Lake Michigan. I am currently the editor of the North American Journal of Fisheries Management and a member of the Board of Technical Experts of the Great Lakes Fishery Commission.
