Sharp-Geiger joins Argonne from DOE’s Los Alamos National Laboratory. In her role as the chief operating officer for Physical Sciences at Los Alamos, she oversaw the advancement, improvement and direction of operational activities enabling fundamental and applied science and engineering for the lab’s national security mission.

Sharp-Geiger has a proven record of successful administration of major facilities and organizational programs. While at Los Alamos, she led the operations management of hazard category 2 and 3 nuclear facilities; nuclear waste facilities, and the lab’s three national user facilities: the Los Alamos Neutron Science Center, the Center for Integrated Nanotechnologies, a DOE Nanoscale Science Research Center and User Facility, and the National High Magnetic Field Laboratory. Her organizational oversight allowed Los Alamos staff to achieve their mission in the areas of homeland security, material discovery, nuclear physics and energy security. She will leverage this extensive experience in her new role.

“Argonne has a strong history of operational excellence, and I’m excited to lead its continued growth, modernization, and innovation,” said Sharp-Geiger. ​“Our efforts will enable the laboratory to continue to open new frontiers for discovery and applied science.”

Prior to her current role, Sharp-Geiger served several other positions at Los Alamos, such as the deputy associate director for operations for Threat Identification and Response; deputy associate director for Environment, Safety and Health; facility operations director for Weapons Facilities; deputy/facility operations director for Environmental Waste Management Operations; and deputy facility operations manager for Materials and Chemistry Facility Operations.

“Rae has the management experience that Argonne needs to maintain its long record of achieving pivotal discoveries, expanding scientific leadership and providing cutting-edge technology at scale,” said Argonne Director Paul Kearns. ​“We are nearing the completion of the construction of the Aurora exascale supercomputer and the upgraded Advanced Photon Source, which when combined will transform how we do science. Rae’s background will enable these powerhouse research tools and our other cutting-edge facilities. Her dedication to developing operations professionals and innovative teams will help us keep accelerating the science that drives U.S. prosperity and security.”
