Ashley Barker serves as the Program Director for the Oak Ridge Leadership Computing Facility at the Department of Energy’s Oak Ridge National Laboratory. Barker oversees day-to-day operations of the OLCF, including progress on the OLCF-6 Project, to deliver the lab’s next supercomputer. The OLCF, a DOE Office of Science user facility, has deployed 4 of the world’s fastest supercomputers in its 29-year history. The facility is managed by the National Center for Computational Sciences division at ORNL, which offers expertise in high performance computing, data, storage, training, and user support for a global user community.

Barker received her bachelor’s degree in English and Master of Science degree in Information Sciences from the University of Tennessee, Knoxville. She joined ORNL in 2009.
