A materials scientist who specializes in superconductors, Sarrao brings a deep background in national lab leadership and the evolution of SLAC science. 

Physicist and scientific leader Sarrao will become SLAC’s sixth director and succeeds X-ray scientist Chi-Chang Kao, who stepped down after 10 years in the position.

Under his leadership, the lab diversified its research portfolio, expanded its science impact, advanced major projects, increased collaboration with Stanford and met the challenges of a global pandemic.

Under his 10-year leadership, the lab has significantly expanded its research and impact.

One of 17 national laboratories supported by the U.S. Department of Energy, SLAC is also marking its 60th anniversary this year.

After decades of experience in the DOE lab system and as director of a leading synchrotron light source, he’s back to where he earned his PhD – with a much bigger mission.

Stephen Streiffer, deputy laboratory director for science and technology at Argonne National Laboratory, has been named as Stanford University’s new vice president for SLAC National Accelerator Laboratory.
