RESEARCH

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.
