Our Research Focus


We study the biodiversity and biogeography of microorganisms, with a focus on picocyanobacteria and picoeukaryotes!


Specific research topics include:


  • Microbial food web dynamics and trophic interactions in eutrophic and oligotrophic waters.

  • Microbial metabolic pathways that are critical to the biogeochemical cycling of carbon, nitrogen, and other elements in the ocean, such as production, respiration, and nitrogen fixation.

  • Effect of climate change and other anthropogenic stressors, such as hypoxia, acidification, and pollutant input on the metabolism of plankton communities.

  • Microbial ecology in cold seep ecosystems.
