My laboratory group studies environmental microbiology, with specialization in urban ecology and water resource management. Research topics include the ecology of sewage-associated microbes in the coastal environment, the response of microbes to aquifer acidification, trace gas production in urban waterways, and the aerosolization of bacteria from polluted waterways. We utilize a broad spectrum of tools including environmental sensors, bacterial cultivation, and molecular genetics to gather data to test experimental hypotheses and to characterize environmental condition.
