Dianne I. Greenfield
Position: Associate Professor
Campus Affiliation: Advanced Science Research Center (ASRC)|Queens College
Degrees/Diplomas: Ph.D Stony Brook University
Research Interests: Biological Oceanography. Coastal and Estuarine Processes, Micro and Molecular Biology, Plankton, Harmful Algal Blooms
I am a biological oceanographer who studies the complex feedbacks between global change (urbanization, nutrients, climate, etc.) and coastal phytoplankton ecology & biogeochemistry. This includes but is not limited to algal blooms, food web processes, and novel molecular technologies. I am always looking for enthusiastic new students. Please contact me via email if you have interest in working in my laboaratory.
