I am a limnologist interested in the ecology of freshwater zooplankton. Themes of my reseach program include: 1) Invasion dynamics of the predatory cladoceran Bythotrephes longimanus in North America, 2) Experimental evaluation of risk-release relationships for non-native species, and 3) Patterns of nutrient flow in the Lake Superior food web. My research program is currently supported by Minnesota Sea Grant, the Great Lakes Maritime Research Institute, the Great Lake Protection Fund, and the University of Minnesota Duluth. I teach General Ecology, Lake Ecology, Plankton Biology, and a Senior Seminar in Public Speaking at the University of Minnesota Duluth as well as a field course called Aquatic Food Webs at the Itasca Biological Station in Minnesota.
