Water Quality and Environmental Biotechnology Laboratory
Our research is in the general areas of water quality and environmental biotechnology, with focused scientific interests in microbial ecology and environmental genomics. Currently, we are most interested in understanding the ecology of fecal indicator bacteria and pathogens in the environment, to identify fundamental principals governing microbial community structure and function dynamics, and to develop innovative biotechnological solutions to environmental and health challenges.

My research is at the interface of water quality and environmental health microbiology. The current research foci include survival of fecal bacteria in water environment, impact of stormwater runoff on coastal water, microbial ecology of non-fecal waterborne pathogens, wastewater infrastructures for infectious disease surveillance, and bacterial antibiotic resistance in natural and built environments.
