Dr. Chris Fall serves as Director of the Department of Energy's Office of Science, the lead federal agency supporting fundamental scientific research for energy and the nation's largest supporter of basic research in the physical sciences. He oversees the Office's two principal thrusts: direct support of scientific research, and development, construction, and operation of unique, open-access scientific user facilities that are made available to external researchers. The Office of Science also is responsible for stewardship of 10 of the Department's 17 national laboratories.

Before joining the Office of Science, Fall served as a Senior Advisor to the Undersecretary for Energy and as Acting Director of DOE's Advanced Research Projects Agency-Energy (ARPA-E). Fall came to DOE from the Office of Naval Research (ONR), where he served for more than seven years in a variety of roles including Acting Chief Scientist and Lead for the Research Directorate, Deputy Director of Research, Director of the International Liaison Office, and the ONR Innovation Fellow. While on loan from ONR, Fall served for three years in the White House Office of Science and Technology Policy as Assistant Director for Defense Programs and then as Acting Lead for the National Security and International Affairs Division. Before government service, Fall was a faculty member at the University of Illinois at Chicago, and he completed postdoctoral fellowships at the University of California at Davis Institute for Theoretical Dynamics and the New York University Center for Neural Science.

Fall earned a Ph.D. in Neuroscience and a B.S. in Mechanical Engineering from the University of Virginia. He also holds an MBA from Northwestern University's Kellogg School of Management.

Deputy Director, Science Programs

J. Stephen (Steve) Binkley is the Deputy Director for Science Programs in the Office of Science (SC) at the U.S. Department of Energy (DOE). In this capacity, Dr. Binkley is the senior career science official in the Office of Science, which is third largest Federal sponsor of basic research in the United States, the primary supporter of the physical sciences in the U.S., and one of the premier science organizations in the world.

As Deputy Director for Science Programs, Dr. Binkley provides scientific and management oversight for the six science programs of the Office of Science (basic energy sciences, biological and environmental research, fusion energy sciences, advanced scientific computing research, high energy physics, and nuclear physics), for workforce development for teachers and scientists, and for construction project assessment. The Office of Science supports research at 300 colleges and universities nationwide, at DOE laboratories, and at other private institutions.

Dr. Binkley has held senior positions at Sandia National Laboratories, the Department of Homeland Security (DHS), and the Department of Energy. He has conducted research in theoretical chemistry, materials science, computer science, applied mathematics, and microelectronics. At Sandia, Dr. Binkley managed computer science, fundamental chemistry, combustion science, and chemically reacting flow organizations. He also has served as the manager for the Office of Science’s Combustion Research Facility, at Sandia's Livermore, California location. Dr. Binkley managed Sandia's Office of Science Program, comprising activities in materials science, chemistry, geoscience, magnetic fusion energy, atmospheric measurement technology, and scientific computing at Sandia’s New Mexico and California locations. He also managed Sandia’s program in distributed information systems technology.

At DOE, Dr. Binkley served as a technical advisor to the Assistant Secretary of Defense Programs (subsequently the Deputy Administrator for Defense Programs after the establishment of the National Nuclear Security Administration). At DHS, Dr. Binkley served as the deputy director for technology within the DHS Operations Directorate, where he led and managed the development of systems for monitoring and disseminating situational awareness to federal, state, and local law-enforcement organizations and for coordinating emergency response activities. Returning to DOE in 2006, Dr. Binkley served as a senior technical advisor to the Under Secretary for Science and the Director of the Office of Science.

As head of SC’s Office of Advanced Scientific Computing Research, Dr. Binkley served as one of the Associate Directors for the Office of Science, and was responsible for the overall management of the ASCR program including: strategic planning; budget formulation and execution; project management; program integration with other Office of Science activities and with the DOE technology offices; and interagency integration.

Dr. Binkley’s present research interests include high-accuracy determination of properties of atoms and molecules, high-fidelity simulation of complex systems such as combustion devices, and the underlying computer science of massively parallel computers and large-data systems.
