Andrew Barton is an Assistant Professor at the University of California, San Diego (Scripps Institution of Oceanography) and at the section of Ecology, Behavior and Evolution of the University of California, San Diego. His research combines observational and numerical modeling perspectives to understand the fundamental mechanisms that regulate microbial population dynamics, community structure, biogeography and biodiversity in the ocean. Barton investigates how changes in Earth’s climate, including natural variability and long-term changes driven by human activities, have the potential to alter microbial species distributions and community composition through time. He received a B.A. in Science of Earth Systems from Cornell University (2000) and a Ph.D. in Climate Physics and Chemistry from Massachusetts Institute of Technology (2011). He was an NSF International Research Postdoctoral Fellow hosted jointly between Duke University and the University of Liverpool in the United Kingdom, and later was an Associate Research Scholar at the Geophysical Fluid Dynamics Laboratory at Princeton University.
