Microbial Ecology and Biogeochemistry

Microbial processes underlie the function of all ecosystems, and yet the vast diversity of microbes in nature is still being discovered. In the Rich lab, we study the structure and function of microbial communities in marine ecosystems. Our research addresses the role of microbes in the flow of elements and nutrients in ecosystems, with a particular focus on the nitrogen cycle. Our field sites are local and remote, from coastal Maine to deep-sea hydrothermal vents, and Antarctica.
