Stephen Streiffer has been named the Associate Laboratory Director (ALD) for Photon Sciences and Director of the Advanced Photon Source (APS) at the U.S. Department of Energy’s Argonne National Laboratory. Streiffer had been serving in both roles on an interim basis since last April.
As part of Argonne’s senior management team, Streiffer will lead the APS as it continues to evolve while serving the user community and maintaining the facility’s international reputation for enabling world-class science.
“Dr. Streiffer is a tremendously accomplished scientist and leader with a strong knowledge of and commitment to Argonne’s mission,” said Argonne director Peter Littlewood. “His strategic vision and technical expertise will provide a strong foundation for securing the future of the Advanced Photon Source and maintaining the laboratory’s position at the vanguard of X-ray science.”
Streiffer joined Argonne in 1998 as a researcher in the Materials Science Division. He was a leading participant in the development of the Center for Nanoscale Materials and served as the center’s Associate Division Director for Science, and later as its interim director.
Streiffer next served as Deputy ALD for the former Energy Sciences and Engineering Directorate, providing leadership for the directorate’s basic sciences portfolio. Subsequently, he helped create the Physical Sciences and Engineering Directorate in 2011 and served as its interim ALD and Deputy ALD, providing day-to-day management of programs that supported the directorate’s strategic priorities.
His scientific expertise centers around developing novel concepts for integration of oxide heterostructures, establishing a fundamental understanding of polar interfaces, and exploring how these interfaces may be manipulated to influence electronic and chemical function. He has authored or co-authored more than 180 scientific publications and holds one patent. He received his Ph.D. degree in Materials Science and Engineering from Stanford University.
