Martha Crenshaw is a senior fellow at CISAC and FSI and a professor of political science by courtesy. She was the Colin and Nancy Campbell Professor of Global Issues and Democratic Thought and professor of government at Wesleyan University in Middletown, Conn., from 1974 to 2007. Her current research focuses on innovation in terrorist campaigns, why the United States is the target of terrorism, the effectiveness of counterterrorism policies, and the organizational development of terrorist campaigns. Crenshaw has written extensively on the issue of political terrorism; most recently, she authored Explaining Terrorism: Causes, Processes, and Consequences (Routledge, 2010) and served as editor of The Consequences of Counterterrorism (The Russell Sage Foundation, 2010). In 2009 Crenshaw was awarded a grant from the National Science Foundation for a project on "mapping terrorist organizations,” which aims to identify patterns in the evolution of organizations that practice terrorism, specify the causes and consequences of these patterns, and analyze the development of Al Qaeda and its cohort in a comprehensive comparative framework. Crenshaw will present on the development and recent findings of this project.
