L. David Smith

L. David Smith is a marine ecologist in the Smith College Department of Biological Sciences and a member of the Environmental Science and Policy Program. His research examines marine biological invasions, the role of phenotypic plasticity (environmentally induced changes) in marine invertebrate predator-prey interactions and coral reef conservation. He teaches courses in biodiversity, ecology and conservation, invertebrate diversity, and environmental science and policy. He chaired working groups that developed the major in Environmental Science and Policy and the Center for the Environment, Ecological Design, and Sustainability (CEEDS) at Smith. He served as director of the Environmental Science and Policy Program from 2005–16 and currently co-directs the Marine Science and Policy minor and the Coral Reef Ed-Ventures Program in Belize.

Smith received a bachelor's degree in biology from the University of Virginia, a master's in marine science from the University of South Carolina, and a doctorate in zoology from the University of Maryland. Prior to joining the faculty at Smith College in 2001, he conducted postdoctoral research at the Smithsonian Environmental Research Center, Bamfield Marine Station in western Canada and the Williams College-Mystic Seaport Maritime Studies Program, and was an assistant professor at Northeastern University.
