Zia Mian is a physicist and co-director of Princeton University's Program on Science and Global Security, part of the Woodrow Wilson School of Public and International Affairs, where he has worked since 1997. He also directs the Program's Project on Peace and Security in South Asia. His research interests include issues of nuclear arms control, nonproliferation and disarmament and international peace and security. He is co-editor of Science & Global Security, the international technical journal of arms control, nonproliferation and disarmament and also co-chair of the International Panel on Fissile Materials (IPFM), an eighteen-country independent group of experts working to strengthen policy initiatives to end production and eliminate stockpiles of plutonium and highly enriched uranium, the key ingredients for nuclear weapons. In addition to his scholarly articles, he is the co-author of Unmaking the Bomb (MIT Press, 2014) and editor of several books and has made two documentary films on peace and security in South Asia. He received the 2014 Linus Pauling Legacy Award for “his accomplishments as a scientist and as a peace activist in contributing to the global effort for nuclear disarmament and for a more peaceful world.” He received the American Physical Society’s 2019 Leo Szilard Award “For promoting global peace and nuclear disarmament particularly in South Asia, through academic research, public speaking, technical and popular writing and organizing efforts to ban nuclear weapons."

Research Interests

 

Zia Mian's work focuses on nuclear disarmament, arms control and nonproliferation issues worldwide. He is working on the implementation of the 2017 United Nations Treaty on the Prohibition of Nuclear Weapons after it enters into force, focusing especially on its disarmament and verification obligations. His work also aims to contribute to the long-standing efforts to achieve an international treaty verifiably banning the production of fissile material for nuclear weapons (FMCT), including through the International Panel on Fissile Materials. Mian directs the SGS Project on Peace and Security in South Asia which has worked since 1997 to inform South Asian nuclear-policy debates through technical and policy research and collaboration and is also part of the effort at SGS to develop a possible resolution of the crisis over Iran’s nuclear program.

Teaching

 

Life in a Nuclear-Armed World (FRS 144). This course looks at what it has meant to live with the bomb for the past seventy years. We use scholarly and popular writings as well as movies and documentaries to understand what it means to make nuclear weapons and to be prepared to use them, how and why the bomb has spread to nine states, the threat of nuclear terrorism, and the links between nuclear weapons and civilian nuclear energy programs. We look also at the economic, political, social, cultural, psychological and environmental costs of a nuclear armed world through the lives of people in nuclear communities and the struggles of the peace movement to ban the bomb. We explore the prospects for the future of nuclear weapons and the implications of the Treaty on the Prohibition of Nuclear Weapons adopted by 122 countries in 2017 at the United Nations. Offered: Spring 2019.
