Education

• Ph.D in Hydrogeology (major) and Wetland Sciences (minor) - University of Wisconsin-Madison, 1993
• M.S. in Hydrogeology - University of Wisconsin-Madison, 1987
• B.A. in Geology (major) and Business (major) - Gustavus Adolphus College, 1985

Areas of Expertise

• My work focuses on groundwater flow, and its effect on natural systems. This research uses a variety of approaches such as numerical modeling, ion and isotope chemistry, tracers, parameter estimation, and stochastic methods. It emphasizes a range of groundwater – surface water systems including wetland, stream, and lake interactions. Recently this work has been extended to research investigating ecohydrology of aquatic systems, effects of climate and landuse drivers, and source and transport of human enteric viruses to drinking water wells.

Current Projects

• Trout Lake WEBB project
• Groundwater Recharge project
• Great Lakes Water Availability Pilot
• Black Earth Creek ground-water/surface-water modeling
• Other project and science support, teaching, and outreach as requested
