Isabelle Williams

Senior Advisor, Global Nuclear Policy Program

Isabelle Williams joined NTI in 2007 and supports the Nuclear Security Project, an initiative led by former Secretary of State George P. Shultz, former Secretary of Defense William J. Perry, former Secretary of State Henry A. Kissinger and former Senator Sam Nunn in their effort to galvanize global action to reduce urgent nuclear dangers and build support for reducing reliance on nuclear weapons, ultimately ending them as a threat to the world.

As part of this work, Williams helps coordinate the international strategy of the Project. This includes managing the work of NSP global partners who conduct a series of activities in their respective countries and regions relating to research, analysis, policy development and public education. She has also helped develop the NSP analytical framework and recently, co-authored "NATO and Nuclear Weapons: Is a New Consensus Possible?" with Steven Andreasen, a long-time NTI consultant and Malcolm Chalmers, a Professorial Fellow at the Royal United Services Institute for Defence and Security Studies (RUSI), which also published the paper. She came to NTI from the Partnership for Global Security, where she managed their next generation nonproliferation program, which included work on Pakistan's nuclear security and U.S. threat reduction budgets.

She was previously a research associate at the Chemical and Biological Arms Control Institute where she focused on research relating to chemical weapons, biosecurity and bioterrorism preparedness and response. She also held successive positions at the International Institute for Strategic Studies in London. Williams holds a bachelor's degree (Hons) and master's degree in International Studies both from the University of Leeds, UK.
