Teaching

I teach Soil Science 230 (Soil: Ecosystem & Resource) each Fall semester. Enrollment averages 70 students, mostly juniors and seniors. Soil Science 230 is designed for students who do not plan to major in soil science. It is cross-listed with two other departments: Geography and the Institute for Environmental Studies.

Research

The issues that interest us relate primarily to the fate and transport of compounds in soil environments. Examples include the binding of metals to humic substances, the sorption of pesticides and other organic compounds to humic substances and the chemical processes that influence the adsorption and distribution of inorganic ions at the mineral/water interface in soils. Our research is supported primarily by the U.S. Department of Agriculture National Research Initiative under the Soils and Soil Biology Program , but we work closely with representatives of the Wisconsin Department of Natural Resources to understand the contamination and remediation problems they face.

Our active programs involve the oxide/water interface of oxide and clay mineral and the colloidal properties of humic substances. Ultimately our experimental program will span the surface and colloidal properties of all soil colloids.

Our approach draws heavily on physical methods, mainly magnetic resonance and x-ray absorption spectroscopies. We initiated a program at the National Synchrotron Light Source (NSLS) at Brookhaven National Laboratory in the fall of 1992. Our synchrotron studies include both XANES and EXAFS studies of metals bound to oxide surfaces and humic substances.

We conduct most of our nuclear magnetic resonance studies at the Nuclear Magnetic Resonance Facility At Madison (NMRFAM), which is supported by the National Science Foundation. Our synchrotron studies include both XANES and EXAFS studies of metals bound to oxide surfaces and humic substances. Our magnetic resonance studies are directed toward understanding pesticide binding to humic substances and the colloidal properties of aqueous humic micellar solutions.

Outreach & Service

I am currently serving the first year of a two year term on the University Academic Planning Council and my first year as a member of the Undergraduate Curriculum Committee for the Institute for Environmental Studies.

As a member of NCR-174, I serve as a representative for the soil science community to the Consortium for Advanced Radiation Sources at the Advanced Photon Source, Agronne National Laboratory.
