Research Interests

Aqueous Environmental Geochemistry. My research explores the behavior of inorganic and organic contaminants in aqueous geochemical settings such as soils, sediments and aquifers. The mechanisms and kinetics of contaminant interactions with common mineral phases determine the mobility and bioaccessibility of these species in natural systems. Understanding these processes has important implications for predicting the fate of contaminant species in the environment.

Specific Interests Include:

Competitive interactions of biologically essential and toxic metals with biominerals
The role of naturally occurring soil organics in contaminant-mineral interactions
Hydrothermal mineralization for recovery of inorganics from polluted waters
Temperature effects of contaminant-mineral interactions
