Sarah Tucker

Sea Grant Knauss Fellow

Sarah Tucker is a 2023 Sea Grant Knauss Fellow working to support the Arctic Research Program and Communications Team in the Global Ocean Monitoring and Observing Program at NOAA. Sarah received her Ph.D. in Marine Biology from the University of Hawai'i at Manoa. Her research focuses on the ecology and metabolisms of a handful of abundant and globally-distributed marine microbes and uses a combination of genomics, time-series sampling, and cultivation. Sarah’s passion for ocean science and conservation comes from the ability to share its curiosities and importance with others. She has been involved in many mentoring, science communication, and capacity building activities and is interested in the community-based research programs.
