Research Interests:
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 developing reactive membrane barriers for pollutant containment,
studying the photochemical fate of pharmaceutical compounds, studying
reactions that occur at mineral (natural) and zero-valent metal (engineered)
surfaces, and using sensor networks to monitor water quality and
predict the presence of organic contaminants in surface waters.
