Thank you Chairman Lummis, Ranking Member Swalwell, and members of the Subcommittee. I am pleased to represent the Department of Energy (DOE) Office of Science at this hearing to discuss the role of the Office of Science in providing tools for scientific discovery and basic energy research.
The DOE Office of Science has long been a leader of U.S. scientific discovery and innovation. Over the decades, the Office of Science has pushed the frontiers of understanding of the origins of matter and the universe; the Office Science has led the world in high performance computing and simulation; we have helped drive the transition from observing natural phenomena to the science of control and directed design at the nanoscale; the Office of Science has played an important role in initiating the modern biotechnology revolution through the initiation of the Human Genome Project; and the Office of Science has built and operated the large-scale scientific facilities that collectively form a major pillar of the current U.S. scientific enterprise. As the federal agency funding the largest fraction of basic research in the physical sciences, the Office of Science will continue to pursue scientific discoveries that provide the technological foundation to extend our understanding of nature and to enable new technologies that support DOE's energy, environment, and security missions.
Today, the Office of Science looks to the future by building on both our historic strengths and unique assets. The Office of Science conducts mission-focused research that employs the capabilities of the national laboratories, universities, and industry to deliver scientific breakthroughs and extend the Nation's knowledge of the natural world.
The Office of Science supports more than 30 national scientific user facilities, which provide researchers with the most advanced tools of modern science, including accelerators, detectors, colliders, supercomputers, light sources and neutron sources, and facilities for studying the nanoworld, the environment, and the atmosphere. Today, about 29,000 researchers from academia, industry, and government laboratories, spanning all fifty states and the District of Columbia, use these facilities to perform scientific research. The Office of Science continues to build on its legacy of excellence in creating and operating world-class, large-scale scientific tools. From the earliest accelerators to the new Linac Coherent Light Source, these facilities continue to redefine what is possible.
The Office of Science is also responsible for the oversight of 10 of DOE's 17 national laboratories: Ames Laboratory, Argonne National Laboratory, Brookhaven National Laboratory, Fermi National Accelerator Laboratory, Lawrence Berkeley National Laboratory, Oak Ridge National Laboratory, Pacific Northwest National Laboratory, Princeton Plasma Physics Laboratory, SLAC National Accelerator Laboratory, and Thomas Jefferson National Accelerator Facility.
