Judith Layzer, Associate Professor of Urban Studies and Planning at MIT, is concerned with how Americans make environmental policy decisions and the impact of science and values on land use and natural resource policymaking. Layzer is currently investigating whether and how collaborative, ecosystem-scale planning yields environmentally protective water and land-use policies. She also investigates the role of business in environmental policy decisions made by the U.S. Congress. She is the author of The Environmental Case: Translating Values Into Policy (CQ Press, 2002).
