Research Interests: The research of our group focuses on understanding how microorganisms catalyze elemental cycling in aquatic systems. A major component of this research involves identifying the types of microorganisms responsible for biogeochemically important processes and studying those processes that control the metabolic activities of these microbes. Our research group uses a variety of tools to study the dynamics of microbial communities, including rate measurements of microbial metabolisms and genetic approaches to study the diversity and activities of microorganisms in nature.
