My research is focused on the fate of anthropogenic chemicals in natural and engineered systems. Most of my efforts are focused on identifying important transformation processes, understanding detailed reaction mechanisms, and determining reaction rates. My goals are to be able to predict contaminant fate in natural aquatic systems and to design remediation technologies to treat contaminated waters. Current efforts include studying the photochemical fate of pharmaceuticals and pesticides, studying reactions that occur at mineral surfaces, remediation techniques for fluorochemicals, detection of micropollutants in aquatic systems, assessment of disinfection byproduct precursors, and developing treatment systems for resource recovery.
