The U.S. Department of Energy’s (DOE) Oak Ridge National Laboratory (ORNL) Site Office (OSO) supports the Office of Science (SC) mission to foster, formulate, and support forefront basic and applied research programs that advance the science and technology foundations necessary to accomplish Department of Energy (DOE) missions. The OSO, under the direction of the SC Deputy Director for Field Operations (DDFO), and in partnership with our program sponsors, customers, contractors, and support organizations, is responsible for implementation of DOE’s mission at the ORNL and the Oak Ridge Institute for Science and Education (ORISE). The OSO responsibility includes the Work for Others performed for Other Federal Agencies, State, and Local Governments and Private Industry performed under the OSO contracts, and other research and development contracts assigned by DOE-Headquarters.

ORNL was established in 1943 as part of the Manhattan Project to pioneer a method for producing and separating plutonium. ORNL has grown into a multi-program National Laboratory with nine National User Facilities and an international reputation for outstanding scientific achievements. National User Facilities include the Building Technologies Research & Integration Center, the Center for Nanophase Materials Science, the Center for Structural Molecular Biology, the High Flux Isotope Reactor, the High Temperature Materials Laboratory, the National Center for Computational Science, the National Transportation Research Center, the Shared Research Equipment User Facility, and the Spallation Neutron Source.

Today, ORNL’s primary mission is focused on conducting research in neutron science, energy, high-performance computing, systems biology, materials science, and national security. ORNL is a unique resource with the distinctive capabilities for addressing technological and scientific challenges both nationally and globally. In addition, ORNL also performs work for agencies other than DOE and private industry enabled by its one-of-a-kind resources.

As a university consortium, Oak Ridge Associated Universities (ORAU) creates and promotes collaborative partnerships among academia, government (with a focus on Oak Ridge National Laboratory), and industry to strengthen the nation’s scientific research and education enterprise.

Also a nonprofit corporation and federal contractor, ORAU provides responsive, innovative solutions to address national needs in the areas of worker/public health and environmental stewardship, emergency response, and scientific research and education. Applying these capabilities, ORAU manages the Oak Ridge Institute for Science and Education for the DOE. 

In addition, as a strategic partner with UT-Battelle, the managing contractor for ORNL, ORAU works with the University of Tennessee and Battelle to help strengthen the science and technology programs at ORNL.

Our purpose is to facilitate mutually beneficial university partnerships that will enhance collaborative research and expand faculty and student participation at the lab.
