Help Support START Research and Education
The START Consortium is dedicated to generating knowledge of the human causes and consequences of terrorism. Applying rigorous standards to both research and education, START seeks to illuminate one of the most highly politicized and understudied phenomena in the social sciences for students, practitioners and policy-makers. Funded primarily through research grants to date, START is seeking to generate an endowment that will provide the flexibility and autonomy to ensure that it can continue to serve as an objective source of data and empirically based analysis into the future.  To donate, or for more information, please click here.
