Phytoplankton ecologist
Sonya Dyhrman is an earth and environmental sciences professor[ 1] who studies the physiology of phytoplankton and their role within marine ecosystems. She is also a fellow of the American Academy of Microbiology.[ 2]
Education and career
Dyrhman grew up in Washington where she spent days clamming on Puget Sound and started scuba diving before she could drive.[ 1] She went to Dartmouth College and received her B.A. in 1994. She then earned her Ph.D. from Scripps Institution of Oceanography , University of California, San Diego in 1999.[ 3] Following her Ph.D., she joined Woods Hole Oceanographic Institution as postdoc and transitioned onto the scientific staff in 2002. In 2014, she moved to Columbia University , Lamont–Doherty Earth Observatory (LDEO) where she is a professor in earth and environmental sciences.[ 4] [ 5]
Research
Dyhrman uses molecular tools to examine phytoplankton in marine systems, with a focus on their ecosystem structure and biogeochemical impact. Her Ph.D. research examined the role of phosphate stress on phytoplankton[ 3] where she identified proteins found in dinoflagellates grown under phosphate-limited conditions[ 6] and then applied this tool to assess phosphate-stress conditions in the field.[ 7] She has examined variability in how phytoplankton consume and produce different forms of phosphorus including dissolved organic phosphorus,[ 8] polyphosphate ,[ 9] and phosphonates .[ 10] Dyhrman has also looked at cell-specific phosphorus stress using Trichodesmium as a model cyanobacteria,[ 11] and specifically examined how use Trichodesmium use phosphonate in the ocean.[ 12] [ 13] A portion of her research interests include investigations into diatoms,[ 14] [ 15] [ 16] cyanobacteria,[ 17] and harmful algal organisms.[ 18] [ 19]
