S&T’s Focus Areas

S&T supports DHS by creating the technologies and solutions needed to strengthen the Homeland Security Enterprise. Working with innovators in federal, state, local, tribal and territorial agencies; private industry; and academia, S&T helps identify, develop or adapt R&D efforts to address strategic needs. The driving force behind all of these efforts is an understanding of the role technology can play in helping the nation’s homeland security officials stay ahead of evolving threats.
