Phytoplankton, microscopic organisms that form the base of aquatic food webs, generate approximately half of the world’s oxygen through photosynthesis and thus exert considerable influence over nutrient and carbon cycling.
Dr. Dianne Greenfield and her laboratory study the complex environmental feedbacks between global change stressors (such as urbanization, nutrients, and climate) and coastal phytoplankton ecology, physiology, and biogeochemistry. This includes but is not limited to understanding the causes and consequences of ‘harmful algal blooms’ (HABs), events produced by a subset of phytoplankton species that result in negative ecological and/or health impacts when populations become numerically or physiologically dominant.
To achieve this goal, Greenfield and her lab develop and apply novel molecular tools to better study plankton populations in situ and combine these advances with traditional field and laboratory approaches. Since phytoplankton dynamics are central to ecosystem productivity, Greenfield and her lab also try to understand their linkages with coastal trophic structure.
Dr. Greenfield joined the Advanced Science Research Center at the Graduate Center during fall of 2017; she also is an Associate Professor in the School of Earth and Environmental Sciences, Queens College. Prior to that time, Greenfield was in Charleston, SC with the Belle W. Baruch Institute for Marine and Coastal Sciences, University of South Carolina with a joint appointment at the Marine Resources Research Institute (SCDNR).
In 2018, Dr. Greenfield was elected to the position of Secretary for the Association for the Sciences of Limnology and Oceanography (ASLO), and serves as CUNY’s representative for the Long Island Sound Study (LISS), Science and Technical Advisory Committee (STAC).
Dr. Greenfield completed her BA from Mount Holyoke College, MS from Tulane University, PhD from Stony Brook University, and a Postdoctoral Fellowship from the Monterey Bay Aquarium Research Institute (MBARI).
Prof. Greenfield is actively searching for talented and enthusiastic students and researchers to join her team. Please contact her at Dianne.Greenfield@asrc.cuny.edu orDGreenfield@qc.cuny.edu if you have further questions. *12/2018 Update* *Dr. Greenfield is searching for a motivated graduate student to work on an exciting new study with the CT and NY’s Sea Grant Long Island Sound Study on regional phytoplankton community dynamics as part of thesis research. Work is expected to begin as soon as possible. Interested prospective students are encouraged to contact Dr. Greenfield for further details.*
