At the WGNHS we strive to conduct science that is useful to the citizens of Wisconsin. We communicate the results of that science to local and state government, private citizens, and other interested parties, such as planning commissions and environmental consultants. My interests include hydrogeology, near-surface geophysics, and physical properties of geologic materials. My areas of research include wellhead protection, water use, the application of near-surface geophysics to geologic and hydrogeologic problems, development of techniques to understand the role of aquitards in flow systems, measuring flows in boreholes, and incorporating geology into the design of geothermal heat pump systems.

My interest in groundwater education has taken me into the classroom. I am an instructor for workshops for teachers who want to learn to use an interactive groundwater model to demonstrate concepts such as flow through various types of materials.
