Research Area: Limnology, Biostatistics, Computer Simulation, Invertebrate Zoology

Research Description:

Dr. Keen's laboratory studies animal plankton in Lake Superior and other surrounding inland lakes. His research focuses on the larger term changes (over decades) of the plankton. More specifically, on their food chain, they are near the bottom, thus, they very significantly affect the "life" of a lake.Dr. Keen's laboratory also developes techniques that help to determine the level of toxicity of both organic and inorganic compounds on plankton.Current Publications:
