I am working to develop model systems for investigating interactions between autotrophic and heterotrophic microorganisms in the sea as I am broadly interested in how the rich functional diversity of marine microbes interacts to cycle vast quantities of organic substrate. Using traditional physiological assays in conjunction with transcriptomics, I hope to uncover new information regarding the metabolic relationship between Prochlorococcus and its associated heterotrophs, and extrapolate this information toward a better understanding of the complex interplay between autotrophic and heterotrophic processes in the marine environment. This work is being coupled to chemical analyses of organic matter produced by Prochlorococcus to provide additional insight into these interactions at the metabolome level.
