CNS offers a prestigious international Visiting Fellows program aimed at full-time professionals with demonstrated interests and engagement in WMD nonproliferation, disarmament and arms control fields, including nuclear, biological, and chemical safety, security and public safety.

Visiting Fellows are typically selected from emerging and developing countries, and could include diplomats, experts, and officials from national governments; experts from think tanks, academia, and industry; researchers/scientists/engineers; university instructors, and other related professionals.

The program is offered on location at the Middlebury Institute of International Studies (MIIS) in Monterey, CA during the Spring semester (early February to mid-May) and again in the Fall (early September to mid-December). Qualified candidates should submit applications by March 31 for the Fall program, and by September 15 for the Spring program.

  • The program is designed to assist junior and mid-career policy and technical professionals to obtain an in-depth understanding of legal, political, regional, and technical aspects of WMD nonproliferation.
  • Develop the skills necessary to have a positive impact on arms control and nonproliferation policy in their respective countries and in the international arena.

      Younger Students

      Participants of 2019

      Summer Undergraduate Fellowship Program

      Participants in the program conduct research on issues related to the spread and control of weapons of mass destruction (WMD), including: nuclear, chemical and biological weapons, and regional security issues in the former Soviet Union, Eurasia, East Asia, South Asia, and the Middle East. Interns may also develop their own research projects under the guidance of senior CNS faculty. The training program starts in June and continues for two to three months. Undergraduate programs include the Summer Undergraduate Nonproliferation Internship and the Davis United World College Fellowship in Nonproliferation.

      Critical Issues Forum for High Schools

      The CIF program is designed to promote awareness of nonproliferation and disarmament issues as well as develop critical thinking skills among high school students from around the world, including the United States, Japan and Russia, through educational outreach activities. Through the program, students develop appreciation and understanding of different national and cultural perspectives on complex but vital international security issues.

      Resources & Tools

      For Educators


      Research by CNS for the Nuclear Threat Initiative (NTI)

      • NTI Education Tutorials: The tutorials were made to build understanding among a new generation of experts and leaders on these often complex issues. The interactive tutorials include overviews of key issues, a glossary, maps, quizzes and more.
      • Countries: Overviews of each country’s nuclear, chemical, biological, and missile programs as well as participation in treaties and regimes
      • Treaties & Regimes: Includes full text documents, country memberships, an analytical overview, and a chronology tracking ongoing work and related developments. All entries are updated regularly, as events warrant.
      • Facilities: Nuclear, chemical, biological, and missile facilities of the countries profiled on the NTI website, often including locations on a Google map.
      • Glossary: Commonly used terms in nonproliferation and disarmament studies.

      Topics of Interest

      Research by CNS for the Nuclear Threat Initiative (NTI)

      • Missile Test Database: Interactive visuals, expert analysis, and raw data concerning ballistic missile and satellite launch vehicle (SLV) launches by North Korea and Iran. The databases are routinely updated. Additional countries may be added in future.
        North Korea  |  India and Pakistan
      • Global Trafficking Database: Nuclear and other radioactive material that has been lost, stolen, or is otherwise out of regulatory control. (Free and open access information)

      Resource Collections

      Research by CNS for the Nuclear Threat Initiative (NTI)

      • 3D Missile Model Collection: Interact with 3D models of ballistic and cruise missiles, organized by country.
      • Civilian HEU Reduction and Elimination Resource Collection: Read research that tracks global civil highly enriched uranium (HEU) holdings, discusses common applications and alternatives, and profiles countries that produce, utilize, or export civil HEU. Included are details of domestic and international efforts designed to address civil HEU security, and remaining implementation challenges.
      • Nuclear Disarmament Resource Collection: Find information and analysis of nuclear weapons disarmament proposals and progress worldwide, including detailed coverage of disarmament progress in countries who either possess or host other countries’ nuclear weapons on their territories.
      • Submarine Proliferation Resource Collection: Discover the submarine capabilities and imports/exports of select countries around the world. The main focus is on technological improvements to global submarine fleets, such as the spread of nuclear propulsion and Air Independent Propulsion (AIP) technologies, which increases the capability of submarines to deliver weapons of mass destruction (WMD). Also tracked is conventional submarine proliferation in potential global flashpoints, particularly the Middle East, South Asia, and Southeast Asia. See also: 3D Submarine Model Collection
      • UNSCR 1540 Resource Collection: Read about Resolution 1540, which requires all states to implement measures aimed at preventing non-state actors from acquiring nuclear, biological or chemical weapons, related materials, and their means of delivery.
