I study phytoplankton...the microscopic algae that give the ocean its greenish color and that photosynthesize, removing CO2 from the atmosphere. Specifically I'm interested in how light, nutrients, and temperature influence phytoplankton growth and taxonomic composition, including the development of "red tides" (harmful algal blooms).
