Research interests

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 and near-surface geophysics. My areas of research include wellhead protection, water use, the application of near-surface geophysics to geologic and hydrogeologic problems, and the development of techniques to understand the role of aquitards in flow 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 (a model is pictured above) to demonstrate concepts such as flow through various types of materials. I am also working on a digital three-dimensional representation of Wisconsin’s aquifers for teachers to incorporate into their lesson plans.

Current projects

Mechanisms of flow across aquitards in southeastern and east-central Wisconsin
Regional hydrogeology of southeastern Wisconsin

I collaborate with faculty and students in the University of Wisconsin-Madison Department of Geology and Geophysics and Department of Civil and Environmental Engineering.

I work with colleagues in the U.S. Geological Survey Wisconsin Water Science Center, Middleton, Wisconsin.

I work with colleagues throughout UW–Extension and the Wisconsin Department of Natural Resources, including faculty and staff at the Center for Watershed Science and Education.
