Dave Gallagher Named 11th JPL Director, Laurie Leshin Stepping Down

Laurie Leshin has decided to step down as director of NASA's Jet Propulsion Laboratory on Sunday, June 1. David Gallagher, who has been serving as the Lab's associate director for Strategic Integration, will assume leadership of the federally funded research and development center, which Caltech manages for NASA.

A distinguished geochemist, Leshin was named by Caltech to lead the lab in early 2022. Her career has spanned academia and senior positions at NASA. Several NASA missions managed by JPL have launched under her leadership, including EMIT, SWOT, Psyche, PREFIRE, Europa Clipper, and SPHEREx, with the NASA-Indian Earth satellite NISAR set for a June launch. In addition, JPL has advanced the development of NASA's asteroid-hunting NEO Surveyor mission as well as the trio of CADRE lunar rovers, and it delivered the Coronagraph Instrument, a technology demonstration with NASA's forthcoming Roman Space Telescope.

"I am proud of the many things JPL has accomplished over the past three years," said Leshin. "In addition to the long list of missions that have launched or moved toward launch during that time, we saved Voyager more than once and flew into history on Mars with Ingenuity. We have made more amazing scientific discoveries than I can name, including finding potential ancient martian biomarkers with Perseverance. And we've driven the forefront of technology on Earth and in space. I know those achievements will continue under Dave's capable leadership."

Leshin, who has also served as Caltech vice president, is stepping down for personal reasons and will remain a Bren Professor of Geochemistry and Planetary Science at Caltech.

"While we respect Laurie's decision to step away from her leadership position at JPL, we will miss her drive, compassion, and dedication," Caltech President Thomas Rosenbaum said. "At the same time, we are grateful to Dave Gallagher for his devotion to JPL and his continuing leadership and partnership going forward. Dave's experience working across multiple government and private sector entities will help secure ongoing support for America's agenda in space, with JPL continuing to play an essential role."

Gallagher will draw on his deep experience at JPL to lead the lab into the future. He arrived at JPL 36 years ago, in 1989, and went on to hold numerous leadership positions. Along with having served as the director and deputy director for Astronomy, Physics, and Space Technology, he was manager of JPL's Advanced Optical Systems Program Office. An electrical engineer, Gallagher also managed the Spitzer Space Telescope and, among other roles, leading the team that built and tested the Wide Field/Planetary Camera 2 (WF/PC-2) — a critical instrument that corrected the spherical aberration on NASA's Hubble Space Telescope.

"Laurie has made a significant impact on energizing and focusing the lab, guiding it back on track after the Covid-19 pandemic. I wish her great success in this next chapter of her career, and I look forward to a very smooth transition at the lab," said Gallagher. "We have exciting opportunities ahead helping to advance our nation's space agenda and a fantastic team to help realize them."

Founded by Caltech faculty and students in 1936, JPL has been managed by Caltech on behalf of NASA since 1958.
