# overview
My research is focused on microbial systems for the degradation of target compounds (hormones, crude oil, petroleum products, explosives, chemical warfare agents, chlorinated agents, among a few others) contaminating soils and waters.  Physical and chemical processes are coupled to the microbial activity to understand the controlling parameters for optimization of performance.  With an interest in improving the link between contaminant concentrations and human exposures for predicting the potential for adverse health effects, my students and I have been working on methods to improve the risk assessment of select compounds.
