START recognized for expanding access for underrepresented students
The University of Maryland’s President’s Commission on Ethic Minority Issues (PCEMI) recently honored START’s education team with an award for its work promoting diversity. In the past few years, START’s Terrorism Studies Program has raised its racial and ethnic minority representation from approximately 20 percent to nearly 40 percent, thereby reaching similar levels of minority student representation as is characterized by the University as a whole. Read more.

A trip to Tohoku inspires new START study abroad program
After planning the trip one year ago, Meredith Collier, START’s Education and Curriculum Development Research Assistant, and 18 University of Maryland students travelled to Tohoku, Japan, where they learned the meaning of kizuna and about the region’s recovery from a magnitude-9 earthquake that killed more than 18,000 citizens in March 2011. Read more.

Technology Transition

With its E2E initiative, START proposes to support this vital DHS mission of ensuring that government officials and law enforcement officers are empowered with the information and resources that they need to prevent violence linked to extremism. More specifically, through a four-year initiative called Supporting CVE Efforts through Resources and Training (CVE R&T), START will:

  1. Develop objective and scientifically validated resources designed to enhance expertise about dynamics of extremist violence for those engaged in CVE efforts at the Federal, state, local and tribal levels, and  
  2. Disseminate CVE training materials and courses rooted in scientific research, throughout DHS and to its partner agencies.
