    Before joining UNIDIR, Ryan was a visiting research fellow with the Arms Control Association where he focused on the intercontinental ballistic missile (ICBM) modernization debate, assisting with briefings to Congressional staff and think tanks in Washington, DC to explain the issues involved in ICBM replacement and the feasibility of removing the ICBM force altogether. He completed a postdoc at Princeton University’s Program on Science and Global Security where he worked on the proliferation risks of laser isotope separation and multinational uranium enrichment in the Middle East. Ryan has a Ph.D. in nuclear physics from the University of Virginia and a B.A. in physics from Kenyon College.
