Professor Lehman received his B.S./M.S. in Biology from Yale University in 1974, and then received the Ph. D. in Zoology from the University of Washington in 1978. He joined the University of Michigan as Assistant Professor in 1978, and became Professor of Biology in 1988. Professor Lehman is recipient of the Henry Russel Award, the highest recognition by the University of Michigan for achievements of junior faculty (1982), and the Distinguished Faculty Governance Award, the highest elected award conferred university-wide by faculty at the University of Michigan (1999).\
Professor Lehman's research publications in international books and journals include nutrient dynamics, microanalytical methods, plankton ecology, primary and secondary productivity, food web structure, and mathematical modeling. He has logged over 300 at-sea ship days as Chief Scientist on research vessels of the U.S. academic fleet (University National Oceanic Laboratory System) operating in the St. Lawrence Great Lakes Erie, Huron, Michigan, and Superior plus additional shipboard research cruises on Lakes Victoria, Edward, and Albert in East Africa. His research has coupled numerical climate forecasts from second generation General Circulation Models (GCM climate projections) with lake physical mixing models and with models for biological productivity of Great Lakes in North America and East Africa. He is currently conducting field research that includes whole lake experiments to control nuisance algal blooms, and building numerical models for river and lake analyses including phosphorus dynamics, nutrient loading from point and non-point sources, internal P cycling, nutrient budgets, and plankton community composition.
Case Studies in Limnology (EEB 401, 2008): A case study approach to limnological principles and environmental problem solving using lakes in North America, Europe, and East Africa as examples.
Oceanography (EEB 380, 1990-2007): Medium-size (ca. 50) course for majors treating organisms and processes of the ocean, including both water and sediment communities. This course includes physical and chemical aspects, but emphasizes biological aspects of oceanography, and applies ecological and evolutionary principles to the study of marine life.
Ecological Knowledge and Environmental Problem Solving (Bio 109, alternate years): Large (ca. 200) course for non-majors that uses a case study approach to teach the elements of scientific reasoning and the limits of scientific methods applied to environmental issues.
Limnology (EEB 483, alternate years): inland lakes, chemistry, geology, biogeochemistry, and ecological principles.
