Current Appointments

Professor and Associate Division Head, Department of Environmental and Biomolecular Systems
Affiliate Scientist, Center for Groundwater Research
Affiliate Scientist, Center for Coastal Margin Observation and Prediction

 

Education

B.A., Chemistry, Williams College, 1980
Ph.D., Applied Chemistry, Colorado School of Mines, 1987

 

Research Interests

Pathways, kinetics, mechanisms, and other fundamental, molecular aspects of environmental oxidation-reduction reactions. The contribution of these reactions to the fate of organic substances under natural conditions, and the enhancement of these processes for application in remediation technologies. The development of quantitative structure-activity relationships (QSARs) for explaining and predicting the properties that affect environmental fate.
