My research interests are in the application of sound statistical methodology to current problems in environmental science. My main source of research funding is from federal agencies (NOAA & EPA) concerned with eutrophication in the Great Lakes.
Since 1982, I have been involved with estimating the annual loading of total phosphorus to the Great Lakes. Lake Erie continues to be of great interest to researchers and regulators, and the information that load estimates provide is indispensable.
Recently, eutrophication symptoms have recurred in all of the Great Lakes and interest in nutrient loadings has renewed. This also includes the study of hypoxia which has always been a problem in the central basin of Lake Erie but has recently been documented in Green Bay.
Other areas of research interest include:
Fish productivity in Wisconsin lakes and streams.
Analysis of mine tailings in National Parks in Utah.
Analysis of total phosphorus concentrations for a TMDL in Big Platte Lake, Michigan.
