Sept. 30, 2010

To: All employees

From: Eric Isaacs, Argonne Director

Subject: Appointment of Interim Laboratory Director for Photon Sciences

It is with great pleasure that I announce the appointment of G. Brian Stephenson as the Interim Associate Laboratory Director for Photon Sciences, effective Oct. 1, 2010.

Brian is recognized worldwide as a leader in x-ray science, with vast knowledge and expertise in synchrotron science, beamlines and instrumentation. Recipient of an R&D 100 Award for his work on the Hard X-Ray Nanoprobe, he has been actively involved in the development of the CD-0 proposal to upgrade the Advanced Photon Source.

Brian currently serves as Senior Physicist and Group Leader of the Synchrotron Radiation Studies Group. He joined the staff of Argonne’s Materials Science Division in 1995.

Brian is co-author of more than 140 publications. He is a Fellow of the American Physical Society and chairs the 2011 X-ray Science Gordon Research Conference. He received B.S. and M.S. Degrees in 1978 from the Massachusetts Institute of Technology, and a Ph.D. in 1983 from Stanford University.

Brian will serve as Interim Associate Laboratory Director for Photon Sciences while a search committee reviews candidates to fill the post. He succeeds Murray Gibson, who is leaving Argonne effective Oct. 1, 2010, to accept a newly created position as Dean of Sciences at Northeastern University in Boston.

Professor Janos Kirz, Scientific Advisor at the Advanced Light Source at Lawrence Berkeley National Laboratory and Distinguished Professor at State University of New York at Stony Brook University, will take over from Brian as chair of the APS Associate Laboratory Director search committee.

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, Office of Basic Energy Sciences (DOE-BES). The APS is the source of the Western Hemisphere’s brightest high-energy x-ray beams for research in virtually every scientific discipline. More than 3,500 scientists representing universities, industry, and academic institutions from every U.S. state and several foreign nations visit the APS each year to carry out applied and basic research in support of the BES mission to understand, predict, and ultimately control matter and energy at the electronic, atomic, and molecular levels in order to provide the foundations for new energy technologies and to support DOE missions in energy, environment, and national security. To learn more about the Office of Basic Energy Sciences and its x-ray user facilities.

Argonne National Laboratory seeks solutions to pressing national problems in science and technology. The nation's first national laboratory, Argonne conducts leading-edge basic and applied scientific research in virtually every scientific discipline. Argonne researchers work closely with researchers from hundreds of companies, universities, and federal, state and municipal agencies to help them solve their specific problems, advance America's scientific leadership and prepare the nation for a better future. With employees from more than 60 nations, Argonne is managed by UChicago Argonne, LLC for the U.S. Department of Energy's Office of Science.
