Laboratory Director, Director's Office
JoAnne Hewett is the director of the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and BSA president. BSA, a partnership between Stony Brook University (SBU) and Battelle, manages and operates Brookhaven Lab for DOE’s Office of Science. Hewett also holds the title of professor in SBU’s Department of Physics and Astronomy and professor at SBU’s C.N. Yang Institute for Theoretical Physics.
Hewett comes to Brookhaven from SLAC National Accelerator Laboratory in Menlo Park, CA, where she most recently served as associate lab director (ALD) for fundamental physics and chief research officer. She also is a professor of particle physics and astrophysics at SLAC/Stanford University.
As Lab director, Hewett oversees a team of more than 2,800 scientists, engineers, technicians, and professionals working to address challenges in nuclear and high energy physics, clean energy and climate science, quantum computing, artificial intelligence, photon sciences, isotope production, accelerator science and technology, and national security.
Hewett is a theoretical physicist. Her research probes the fundamental nature of space, matter, and energy. She is best known for her work on physics beyond the Standard Model of particle physics and how that might relate to experiments.
Hewett earned her bachelor’s degree in physics and mathematics and Ph.D. in physics from Iowa State University.
Hewett has twice been a member of the High Energy Physics Advisory Panel—which advises the federal government on the national program in experimental and theoretical high energy physics (HEP) research—and served as the panel’s current chair 2018-2023. She made major contributions to the 2014 Particle Physics Project Prioritization Panel ("P5") plan that defines priorities for U.S. high-energy physics research over the next 10 years. She also has served on the program advisory committees for SLAC, Fermi National Accelerator Laboratory, the Kavli Institute for Theoretical Physics, and the Cornell Electron Storage Ring.
Hewett is a fellow of the American Association for the Advancement of Science and the American Physical Society. She served as chair of the American Physical Society’s Division of Particles & Fields in 2016.
