Research Interests:  Ecology, evolution and systems biology of Pelagibacterales (SAR11) marine bacteria; new technologies for culturing bacteria; the marine carbon cycle.

Courses Taught:  MB 420/520 Microbial Genomics, Biogeochemistry and Diversity; MB 668 Microbial Bioinformatics and Genome Evolution.  


We study how biology interacts with the atmosphere and the oceans to change global patterns in the movement of carbon and other elements.  Our experiments begin at sea, but we carry this research into the laboratory, where we work with microbial cells and genome sequences to discover new cell types and new biochemical transformations of matter.  Our goals are to understand how these extraordinary cells evolved, how they function, and how planktonic ecosystems will change in response to ocean warming.
