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.
Research Interests
- Ocean Carbon Cycle
- Marine Microbiology
- Microbial Genome Evolution
High Throughput Cultivation Laboratory
Dr. Stephen Giovannoni founded Oregon State's HTCL, which pioneered automated methods for isolating and studying the elusive microbes that often dominate natural ecosystems. His research team developed SAR11 cell culture as a model system for studying the oceanic carbon cycle and streamlining, a path to minimal complexity in microbial cell architecture. His research also focuses on the role of SAR202 marine bacteria in ocean carbon sequestration, and biochemical mechanisms of ocean deoxygenation.
