Research Interests:

Moran lab research focuses on how marine bacteria process and transform organic carbon and sulfur, and how interactions between bacteria and phytoplankton affect these transformations, including the formation of climate-relevant gases. Our research leverages tools from molecular microbial ecology and ecological genomics, in both laboratory model systems and natural marine environments.
