Los Alamos National Laboratory

Los Alamos National Laboratory (LANL) is a multidisciplinary research institution operated for the U.S. Department of Energy's National Nuclear Security Administration (NNSA). Established in 1943, the Laboratory is dedicated to advancing science and technology in support of national security while addressing some of the world's most complex scientific and engineering challenges. By integrating expertise across physics, chemistry, engineering, computer science, materials science, and advanced computing, LANL delivers innovative solutions with national and global impact.

A core mission of Los Alamos is maintaining the safety, security, and effectiveness of the U.S. nuclear deterrent through the Stockpile Stewardship Program. Using advanced computational modeling, experimental science, and engineering, the Laboratory assesses the performance of the nation's nuclear stockpile without underground nuclear testing. World-class capabilities in high-performance computing, materials science, and nuclear physics enable LANL to develop predictive models and technologies that support stockpile modernization and long-term national security.

LANL is also a leader in advancing peaceful nuclear energy technologies. Research focuses on next-generation reactors, including small modular reactors, advanced nuclear fuels, reactor materials, isotope production, and nuclear chemistry. By combining experimental research with computational modeling, the Laboratory develops technologies that improve reactor safety, efficiency, and sustainability while supporting clean energy and energy security objectives.

Artificial intelligence is a rapidly expanding capability across the Laboratory. LANL develops trustworthy AI and machine learning methods that accelerate scientific discovery, enhance computational modeling, improve data analysis, and strengthen decision support for national security applications. Researchers integrate AI with some of the world's most advanced high-performance computing systems to solve complex problems in nuclear science, materials research, cybersecurity, and engineering. The Laboratory also emphasizes explainable, secure, and reliable AI for high-consequence scientific and operational environments.

Los Alamos is internationally recognized for its leadership in safeguards science and technology, supporting nuclear nonproliferation and global security. The Laboratory develops advanced radiation detection systems, nuclear material accounting methods, environmental monitoring technologies, remote sensing capabilities, and analytical tools that help verify the peaceful use of nuclear materials. AI and advanced data analytics further enhance safeguards by improving the analysis of information from sensors, satellite imagery, and other data sources to strengthen nuclear verification and detect anomalous activities. LANL also contributes to treaty verification technologies and collaborates with domestic and international partners to reduce nuclear threats and strengthen global nuclear security.

The Laboratory's multidisciplinary culture enables scientists and engineers from diverse fields to work together on challenges that span traditional boundaries. Strong partnerships with universities, industry, government agencies, and international organizations accelerate innovation while supporting workforce development and technology transition.

Today, Los Alamos National Laboratory continues to advance scientific excellence in support of national security, nuclear energy, artificial intelligence, and safeguards science and technology. Through cutting-edge research, world-class computational capabilities, and interdisciplinary collaboration, LANL develops innovative solutions that strengthen national security, advance clean energy, and contribute to a safer and more secure world.
