George Srajer Appointed APS Upgrade Project Director

Argonne National Laboratory Director Eric Isaacs has appointed George Srajer to the position of Project Director for the Advanced Photon Source (APS) Upgrade project, and Deputy Associate Laboratory Director of Facility Development for Photon Sciences, effective immediately.

George has been with the APS since joining Argonne in 1991, during the original APS construction project. He has a strong background in developing and managing x-ray science programs and facilities, most recently as Associate Division Director in the X-ray Science Division. George has served as the leader for Argonne's Hard X-ray Sciences Strategic Initiative. He has also served as a group leader for polarization studies and as a physicist and assistant physicist at Argonne.

George received his Ph.D. in physics from Brandeis University and performed postdoctoral studies at Bell Laboratories. He is a fellow of the American Physical Society and a member of the Materials Research Society.

“George brings a wealth of knowledge and expertise that will be key to the continued success of the APS Upgrade project,” said Isaacs. “Please join me in thanking Derrick Mancini for his contributions to the APS Upgrade project over the past 20 months as its founding project director, including securing CD-1. As I know you will, please give your support to George in his new position.”

In announcing the appointment to the APS staff, APS Director Brian Stephenson said, “George has a distinguished history of service at APS, beginning in 1991 and most recently as Associate Division Director in the X-ray Science Division. His experience and leadership will be key to our success as we move into the next phase of the Upgrade project.

“I'd like to thank Derrick Mancini for his foundational contributions in developing the Upgrade project to this point, and welcome George to his new role in this critical endeavor.”

The Advanced Photon Source at Argonne National Laboratory is one of five national synchrotron radiation light sources supported by the U.S. Department of Energy’s Office of Science to carry out applied and basic research to understand, predict, and ultimately control matter and energy at the electronic, atomic, and molecular levels, provide the foundations for new energy technologies, and support DOE missions in energy, environment, and national security.
