My research interests include microbial ecology and environmental microbiology and its interface with both public and ecosystem health. I have worked on issues ranging from water and sanitation to climate change to coral disease ecology. Currently, my lab is focused on understanding population dynamics of Vibrio in the context of its response to episodic events in tropical waters. We are also working on unraveling mechanisms of coral disease, especially among the threatened coral Acropora palmata in the Caribbean. Closer to home in Athens, we are also working on water quality impacts in rural and urban streams and investigating the role of landscape in the persistence and transmission of enteric pathogens.
