Jill Hruby


Jill Hruby was sworn in by U.S. Secretary of Energy Jennifer M. Granholm Monday as the Department of Energy’s (DOE’s) Under Secretary for Nuclear Security and Administrator of the National Nuclear Security Administration (NNSA).

“I am so grateful to the Senate for confirming Jill Hruby to serve as the next Under Secretary for Nuclear Security and Administrator of the National Nuclear Security Administration,” Secretary Granholm said. “Jill is one of DOE’s very best success stories — rising through the ranks at Sandia National Labs to become the first woman to lead a national security lab, and now she’ll lead our efforts to maintain a safe and reliable nuclear deterrent and protect our national security. She is a brilliant leader, a model public servant, and an inspiration to engineers and rising stars everywhere. I am thrilled to have her back at DOE to help keep our nation and our world safe.”

Hruby started her career as a member of the technical staff at Sandia National Laboratories (Sandia) and rose through the ranks to become the first woman to lead an NNSA national security laboratory. “I am honored by the confidence that President Biden and Secretary Granholm have shown in me to lead NNSA,” Hruby said. “I look forward to working with this team to ensure our national capabilities are unparalleled, our partnerships are enduring, creative solutions are found for our challenges, and we deliver our commitments to the American people.”

Hruby retired from Sandia in 2017 after a distinguished 34-year career there. Since then, she has remained active in exploring the intersection of emerging technology with national security policy through her work with non-governmental organizations, the National Academy of Sciences, the Defense Science Board, and other boards and advisory committees. Most recently, she was the Nuclear Threat Institute’s inaugural Sam Nunn Distinguished Fellow.

She earned her bachelor’s degree from Purdue University and her master’s degree from the University of California at Berkeley, both in mechanical engineering. She has authored many publications and reports, holds three patents, and received numerous awards.
