The Center for Nonproliferation Studies (CNS) is one of several research centers based at the Institute. It is the largest nongovernmental organization in the United States devoted exclusively to research and training on nonproliferation issues. Students benefit from CNS by getting access to top experts who frequently come to campus to speak, as well as being able to work as research assistants. Researchers at CNS are frequently called upon by the media to weigh in on important nonproliferation and security issues.
