Message from Eric Isaacs: Stephenson Named APS Director

To the APS User Community,
I'm extremely pleased to announce that Brian Stephenson has been appointed Associate Laboratory Director (ALD) for Photon Sciences, effective September 1, 2011. The directorate comprises three research and support divisions centered on Argonne’s Advanced Photon Source (APS).

As you know, Brian has been interim ALD for Photon Sciences since October 2010, proving his abilities to lead both the directorate and the Advanced Photon Source Upgrade project effort. He is a recognized and widely known world leader in X-ray science with vast knowledge and expertise in synchrotrons, beamlines, and instrumentation. He received an R&D 100 award for his work on the Hard X-ray Nanoprobe, served on the APS User Steering Committee and was a critical team member in the development of the initial proposal to upgrade the Advanced Photon Source.

Brian joined Argonne in 1995, serving most recently as Senior Physicist and Group Leader of the Synchrotron Radiation Studies Group in the Materials Science Division and as Director of the Nanoscale Materials Collaborative Access Team at the APS. Previously, he worked at IBM’s T.J. Watson Research Center, first as a research staff member, then as manager of the Statistical Physics Group. From 1987 to 1995, he was spokesperson for the IBM-MIT Participating Research Group at the National Synchrotron Light Source. From 1990-1994, he led the IBM-MIT-McGill Collaborative Access Team at the APS. Brian is the co-author of more than 140 publications. He is a fellow of the American Physical Society and was the chair of the 2011 X-Ray Science Gordon Research Conference.

To quote Bill Stirling, Chair of the APS Scientific Advisory Committee and Director-General of the European Synchrotron Radiation Facility from 2001-2008: "It was a great pleasure, both as a synchrotron X-ray scientist and as Chair of the APS Scientific Advisory Committee, to hear of the appointment of Brian Stephenson as Associate Laboratory Director for Photon Sciences. Brian is recognized internationally as a leading expert in the field of synchrotron science, with a particular interest in the development of novel synchrotron X-ray techniques. I look forward to working with Brian during the implementation phase of the APS Upgrade, a project to which he has made many important contributions."

Please join me in congratulating Brian and lend him your full support as he begins this challenging assignment.

Best regards,
Eric Isaacs Director, Argonne National Laboratory
