Microbial interactions are key in many global biogeochemical cycles. One remarkable example is dense algal blooms in the ocean that harbor a rich bacterial population. The microbial community in these blooms shares a complex network of relations between microbes, and with the environment. To elucidate some of this complexity I study a model system of algal-bacterial interactions. I am interested in achieving a comprehensive view of how the microorganisms affect each other’s physiology and how their interaction influences biomarkers that are preserved in the geological record. My research employs experimental approaches from both microbiology and Earth sciences.
