  • Research Assistant, Greenfield Lab, Environmental Sciences Initiative

Jessica Espinosa is a Research Assistant in Dr. Dianne Greenfield’s lab in the GC-ASRC’s Environmental Sciences Initiative. She recently earned an M.A. in Ecology, Evolution, and Conservation Biology at Columbia University in May 2018, and in 2015 she earned a B.A. in Biology from Mount Holyoke College.

In the Greenfield lab, she is currently helping investigate the causes and consequences of harmful algal blooms and is working on other projects involving phytoplankton ecology, physiology, and biogeochemistry. While at Columbia University, her thesis focused on the effects of coastal pollution on the behavior and morphology of hermit crabs in the Republic of Fiji. She also did work studying microplastics in coastal systems, stable isotope variation with coastal pollutants, and changes in perception of mangroves across Fiji. Her undergraduate thesis looked at the sex ratio and body condition of female fiddler crabs along the eastern coast of the United States.
