The main objectives of our research is to (1) understand how bacteria adapt to different environmental conditions and (2) how the resulting diversity influences global biogeochemical cycles. Most of the work is done on the unicellular marine cyanobacteria Prochlorococcus and Synechococcus, but we are also interested in other organisms. The goal is to understand the relationship between variation in the physical environment, genome composition, and phylogeny - and how that all ties to together in shaping biogeochemical cycles.
Here is a list of some current projects:
We also work on several projects that are more general and not specifically focused on marine bacteria. This includes examining how bacteria respond to simulated global change in a terrestrial grassland ecosystem.
