The event is the fourth part of a yearlong series celebrating Maine women. Leslie will discuss the connections among people and coastal ecosystems, and focus on how marine scientists use a combination of field experiments and modeling to investigate how climate and changes in economic and regulatory policy influence ecosystems and social interactions. An international leader in marine conservation science, Leslie conducts research on the ecology, policy and management of coastal ecosystems. She is director of the University of Maine’s marine laboratory, Darling Marine Center, and professor of marine sciences. She studies a wide array of marine and environmental science topics, including aquaculture and marine fisheries.
