My research program examines several aspects of fisheries ecology. Current projects are focused on studying the interactions between exotic and native fishes, the effects of climate change on habitat quality for cold water fishes, nutrient regeneration and ecology of vertically migrating fauna in Lake Superior, individual based modeling and stream ecology. While this group of topics is diverse, each is important for they are focused on examining the influence of human induced environmental change on aquatic communities. Fish populations are a vital source of revenue for economic interests in sport and commercial fisheries, as well as a vital link in ecosystem processes that influence water quality. Understanding linkages between aquatic species and ecosystems is vital to predicting the effects of changing the natural environment.
