"Sue is an extraordinarily talented and accomplished professional. She's ideally suited to help achieve our ambitious goals and complex regulatory environment," Anastasio said.
Stiger, who has managed environmental cleanup operations at some of the U.S. Department of Energy's most challenging and complex sites, joins the Laboratory from Idaho National Engineering Laboratory.
Stiger saved taxpayers billions of dollars by safely and dramatically accelerating cleanups at Idaho National Engineering Laboratory and the Rocky Flats Site near Denver while meeting stringent regulatory requirements. Her Idaho team safely shipped nearly 15,000 drums of transuranic waste to DOE's Waste Isolation Pilot Plant in 27 months rather than the four years originally scheduled.
Stiger developed disposal strategies for DOE's largest inventory of mixed and low-level waste, at Oak Ridge Reservation in Tennessee, where she achieved the Reservation's first offsite shipment of low-level waste. She also accelerated completion of the transfer of spent nuclear fuel from the damaged nuclear reactor at Three Mile Island to safe long-term storage.
"Sue has worked closely with regulatory agencies to accelerate cleanups-and in a manner that's highly protective of public safety and natural resources," said Anastasio. "Her leadership will help ensure that we demonstrate excellence in environmental stewardship."
Stiger has 30 years of experience in engineering, environmental restoration, waste management, and decontamination and decommissioning, the last nine years associated with Bechtel National Inc. She earned a civil engineering degree from the Massachusetts Institute of Technology.
Los Alamos National Laboratory, a multidisciplinary research institution engaged in strategic science on behalf of national security, is operated by Los Alamos National Security, LLC, a team composed of Bechtel National, the University of California, The Babcock & Wilcox Company, and Washington Group International for the Department of Energy's National Nuclear Security Administration.
Los Alamos enhances national security by ensuring the safety and reliability of the U.S. nuclear stockpile, developing technologies to reduce threats from weapons of mass destruction, and solving problems related to energy, environment, infrastructure, health, and global security concerns.
