I have been at Lewis & Clark College since Fall 1993.
Courses I have taught include Physical Chemistry (Thermodynamics & Kinetics; Statistical Mechanics & Quantum Chemistry), Physical Chemistry Laboratory, Perspectives in Environmental Chemistry, General Chemistry I and II, Aquatic Chemistry, and Exploration & Discovery.
Research in my group focuses on environmentally relevant electrochemical reactions; currently we are examining the effect that clay has on the oxidation of iron metal. This work has applications to the improvement of iron permeable reactive barriers used for the degradation of groundwater contaminants as well as the corrosion of iron structures in soils (e.g. nuclear waste containers). In our research, we coat iron electrodes with a clay suspension. We then use electrochemical techniques (linear sweep voltammatry and electrochemical impedance spectroscopy) to determine how the presence of the clay affects the iron oxide film on the iron and the corrosion of the underlying iron metal. My first student to work on this project was profiled in an article in the “Lewis & Clark Chronicle”, An Electrochemical Investigation of the Enhanced Reactivity of Clays in Contact with Iron Metal.
