I am an aquatic microbial ecologist that uses experimental and computational techniques to understand the role of top-down (e.g. viral infection) and bottom-up (e.g. nutrient limitation) factors on microbial communities. Specifically, I am interested in understanding the interactions between phytoplankton and their heterotrophic bacterial partners that influence the productivity of algal biofuels. My current projects focuses on characterizing the role of iron limitation on community phycosphere dynamics and determining how virus infection alters the interactions between bacteria and diatoms.
