Katie Cramer is an Associate Research Professor at the Julie Ann Wrigley Global Institute of Sustainability at Arizona State University, an Ocean Science Fellow at the Center for Oceans at Conservation International, and a National Geographic Explorer. Katie is a marine conservation ecologist whose work reconstructs long-term change in marine ecosystems and predicts their future states to motivate and inform conservation. Her current research is focused on improving the health of coral reef ecosystems by pinpointing the social and ecological mechanisms of recent declines and identifying strategies that can improve the sustainability of coral reef fisheries and the food security of reef-dependent communities. Her work is interdisciplinary, spanning the fields of marine ecology, paleobiology, marine policy, and fisheries science.
Katie received her Ph.D. in Oceanography from Scripps Institution of Oceanography. Prior to joining ASU, she was a Knauss Marine Policy Fellow in the U.S. Senate, an ecologist at Global Coral Reef Monitoring Network, and a Postdoctoral Fellow at Smithsonian Institution and Scripps Institution of Oceanography.
