Defense and Security Studies at Columbia University advances understanding of global security through research, analysis, and programs. Since 2013, DSS has led and convened conferences, workshops, and seminars on contemporary defense challenges.

DSS plans and develops programs with consortium universities—Brown, Dartmouth, the University of Chicago, Cornell, Duke, Harvard, MIT, the University of Pennsylvania, Princeton, Stanford, and Yale—and with consortium partners from the U.S. National War College, U.S. Army War College, U.S. Naval War College, U.S. Military Academy at West Point, and U.S. Naval Academy.
