Founded in 1946, Argonne National Laboratory is a U.S. Department of Energy national laboratory located in Lemont, Illinois, operated by UChicago Argonne LLC on behalf of the government. It evolved from the University of Chicago’s wartime Metallurgical Laboratory, which underpinned early nuclear research. Argonne is distinguished for its broad portfolio in physical sciences, energy, materials, computing, environmental and biological sciences, and national security. Its mission is to deliver science and technology solutions to national challenges — from sustainable energy and climate resilience to advanced computing and security. The laboratory hosts world-class facilities (e.g. the Advanced Photon Source, Center for Nanoscale Materials, leadership computing) and undertakes both fundamental and applied research across multiple domains.
