The Nuclear Threat Initiative (NTI) is a nonprofit, nonpartisan global security organization based in Washington, DC, focused on reducing nuclear and biological threats and other emerging-technology risks that could imperil humanity. NTI frames its mission as transforming global security by driving systemic solutions to these threats, and operates by convening governments and experts, producing policy-relevant analysis and public benchmarks, and supporting programs intended to produce durable changes in security practices and decision-making.
NTI’s current program structure is organized around (1) Global Nuclear Policy, (2) Nuclear Materials Security, (3) Global Biological Policy & Programs (NTI | bio), and (4) Communications; and it also runs an AI & Tech program area centered on how rapidly evolving capabilities (including at the intersection of AI and the life sciences) could change risk profiles. A signature element of NTI’s approach is benchmarking and index-style public assessments. For example, NTI’s Nuclear Security Index is positioned as a public benchmark of nuclear security conditions across countries, and NTI | bio’s Global Health Security Index assesses national capacity to prevent, detect, and respond to pandemic threats (with associated work to track improvements and highlight gaps). Strategically, NTI is in a leadership transition phase that began with the board-announced 2025 transition involving Ernest J. Moniz and Joan Rohlfing stepping down from NTI roles in 2025, followed by the appointment of Christine E. Wormuth as President and CEO effective November 17, 2025. This leadership posture is reflected in continued focus on nuclear risk reduction dialogues and on governance challenges around emerging biotechnologies and AI-enabled bio capabilities.
