George Srajer
Acting LANSCE User Facility Director

George Srajer is acting director of the Los Alamos Neutron Science Center (LANSCE) and senior director for the Physical Sciences Directorate at Los Alamos National Laboratory (LANL). LANSCE is a premier accelerator-based user facility for research underpinning Laboratory missions in national security, energy security, and fundamental science—with over 700 user visits annually. George has overall operational responsibility for LANSCE and oversees the basic, applied, and national security research performed at the 5 target stations that comprise LANSCE—including neutron scattering research at the Lujan Neutron Scattering Center, nuclear science and technology at the Weapons Neutron Research Facility, national security research at the Proton Radiography Facility, fundamental research at the Ultracold Neutron Facility, and the production of research, industrial, and medical radionuclides at the Isotope Production Facility.
George joined LANL in 2021 as deputy project director for the Advanced Sources and Detectors (ASD) project. During his tenure, he also served as technical director, LANL senior team lead, and, most recently, as acting project director. As technical director, George oversaw completion of the project’s final design, development of the Final Design Report, and the successful technological maturation work that were critical for Department of Energy (DOE) approval of critical decision‑2/3 (Approve Performance Baseline/Approve Start of Construction) in November 2022.
Before joining ASD at LANL, George spent 30 years at the Advanced Photon Source (APS) at Argonne National Laboratory in various leadership and management roles. George has extensive experience in managing user facilities. He was deputy associate laboratory director for photon sciences, responsible for the operation of the APS, the largest user facility in the U.S. George also led the APS Upgrade Project for two years as project director through the CD-2 review. In addition, he served as project director for the Dynamic Compression Sector (DCS) at the APS, successfully delivering DCS on budget, within scope, and ahead of schedule.
George holds a PhD in condensed matter physics from Brandeis University and completed a postdoctoral appointment at AT&T Bell Laboratories. He has authored 105 scholarly articles, 1 book chapter, and 4 patents. George has advised four PhD students, supervised nine postdoctoral appointees, and one high school student. He is the recipient of the University of Chicago Board of Governors Distinguished Performance Award and is a fellow of the American Physical Society, Division of Condensed Matter Physics.
