Phytoplankton ecology and physiology, bacteria-phytoplankton interactions, developing and improving methods for investigating marine phytoplankton from the cellular to global scale.

  • My research interests range from cellular to global scale processes related to phytoplankton ecology.  I employ innovative methods and state of the art imaging and instrumentation to investigate the interactions of phytoplankton with their environment and other organisms (e.g. cell-cell interactions between phytoplankton and bacteria including the human pathogen Vibrio cholerae). Recent work resulted in the first direct field measurements of phytoplankton carbon.  These measurements are being applied to evaluate bio-optical relationships with phytoplankton biomass, investigate phytoplankton photophysiology, and estimate trophic interactions and carbon cycle dynamics in the surface mixed layer of the marine environment.

Jason Graff is an Assistant Professor in the Department of Botany and Plant Pathology at Oregon State University in the Phytoplankton Ecophysiology Lab. He earned his Ph.D. (2010) from The Graduate School of Oceanography at the University of Rhode Island, investigating particle colonization with an emphasis on the processes regulating the interactions of pathogenic bacteria with marine phytoplankton. Dr. Graff’s current research focuses on phytoplankton carbon stocks, physiology, in-water optics and satellite remote sensing applications.
