- Masters Student, Greenfield Lab, Environmental Sciences Initiative
Zabdiel Roldan Ayala graduated from the University of Puerto Rico at Humacao with a Bachelor’s degree in coastal marine biology. He is currently a graduate student in the School of Earth and Environmental Science doing a Master’s in Geological and Environmental Sciences. He currently works at the Advanced Science Research Center as a research assistant in Dr.Greenfield’s lab. Zabdiel’s research interests involves understanding the ecology and physiology of marine phytoplankton and how these organisms can be indicators of climate change.
