John J. Rehr is an American theoretical physicist, professor emeritus of physics at the University of Washington in Seattle.^[3] He has worked in the field of theoreticalX-ray^[4][5] and electron-spectroscopies.

Biography

Rehr received a B.S.E. in 1967 from the University of Michigan, followed by a Ph.D. from Cornell University, in 1972, in theoretical condensed matter physics with David Mermin as his advisory. He then held a NATO postdoctoral fellowship at King's College London and at University of California, San Diego, with Walter Kohn.

In 1975, he was appointed assistant professor in the Department of Physics at the University of Washington, rising to the rank of associate professor in 1980 and full professor in 1985. Rehr has held visiting appointments at Cornell University, Freie Universität Berlin, Lund University, Université de Poitiers and L'École Polytechnique (Paris). He has been a consulting professor at the Stanford Synchrotron Radiation Lightsource, Co-ordinator of the DOE Computational Materials Science Network, and leader of the Theoretical X-ray Beamline of the European Theoretical Spectroscopy Facility.^[6]

Work

His works have received over 22,000 citations.^[7] His research specialties are in condensed matter theory, particularly in the field of excited state electronic structure and the theory of X-ray and electron spectra.^[8][9] One of Rehr's major accomplishment was the theoretical solution of the EXAFS problem,^[10][11] and quantitative theories of core-level x-ray and electron spectroscopies. Rehr is also the founding father of the first principles code FEFF8 and the principal investigator of the FEFF project. Rehr group's FEFF^[12][13] codes are in use worldwide and currently has over thousands of subscription.

Rehr has also led his team in developing next generation scientific computation on cloud computing platforms; their FEFF programs are available in the Amazon Web Services cloud for the physics community.^[14] FEFF leverages Amazon Elastic Compute Cloud Computer instances to enable physicists all over the world to access on-demand High Performance Computing resources.

His research is supported by the US Department of Energy BES, the DOE Computational Materials and Chemical Sciences Network (CMCSN)^[15]

Honors and awards

Rehr received the Arthur H. Compton Award^[16] in 2011 and the International XAFS Society's Achievement Award in 2006.^[17] He was elected a Fellow of the American Physical Society in 2001.^[18]
