Ryan Rykaczewski
Ph.D., Biological Oceanography
2011-2012 Senior Research Fellow (Princeton University)
Supervisory Marine Scientist, NOAA Fisheries, Hawaii
Assistant Professor, University of South Carolina
Ryan Rykaczewski, assistant professor at the University of South Carolina’s Marine Science Program and Biological Sciences program, focuses his research on the responses of ecosystem and fisheries production to past and future climate variability and climate change. This research involves consideration of theory, observations, and models. He holds a PhD from the Scripps Institution of Oceanography at the University of California, San Diego.
