The Homeland Security Project at Harvard Kennedy School’s Belfer Center for Science and International Affairs is pleased to announce the creation of a paper series examining current and critical issues in homeland security. The Homeland Security Project seeks a variety of viewpoints, and the paper series is non-partisan. The intended audience for the paper series is broad, including policymakers in Congress and the Executive Branch, the homeland security community, and the general public. This call for papers is open to policy practitioners, scholars, the private sector, and non-governmental organizations.
