  Yuji Arai
Clemson University, Department of Entomology, Soils and Plant Science, Clemson, S. Carolina, 29634-0315
  Assistant Professor of Environmental Soil Chemistry at Clemson University in Clemson, SC. Since 1997, he has been conducting molecular environmental soil chemistry research using bulk- and microfocused(µ)-XAS, µ-XRF and µ-XRD techniques at ALS, APS, NSLS, and SSRL. His major research interest is to understand the molecular scale chemical reactions of nutrients, metal(loid)s, and radionuclides at the soil mineral-water interface that is responsible for the field-scale transport processes. He is interested in developing an interdisciplinary molecular environmental soil chemical research program through academia. He would like to represent the voice of users to further improve the BL capabilities and the accommodation of SSRL user facilities.

  Katherine A. Kantardjieff (Vice Chair)
CSU Fullerton/Keck Center for Molecular Structure
  Professor of Chemistry and Biochemistry at California State University Fullerton, is Director of the W.M. Keck Foundation Center for Molecular Structure. She completed Ph.D and postdoctoral work in physical chemistry and structural biology at UCLA with David Eisenberg. Kantardjieff's laboratory is the only member of the Tuberculosis Structural Genomics Consortium from a non-PhD granting institution. CMolS is comprised of comprehensive X-ray diffraction and computational laboratories supporting research and education as a core facility in the 23-campus CSU, as well as the STaRBURSTT-CyberDiffraction Consortium, a nationwide virtual organization of predominantly undergraduate institutions. CMolS pioneered the use of remote instrumentation access at PUIs and, since 2006, CMolS is a research partner with SSRL. Kantardjieff's own research investigates protein structure and function, employing combined experimental and in silico approaches of crystallography, biophysical methods, computation and informatics. The knowledge gained is applied to the engineering of molecules with specific properties, and to structure-guided drug design. Systems of current interest include bacterial cytochromes c', carbonyl reductases, cholinesterases and several tuberculosis proteins. Kantardjieff and collaborators at Fullerton have established a research computing cluster for computational biochemistry and crystallography, which is part of a larger CSU system-wide, distributed computing resource. Kantardjieff has developed and deployed crystallography and computational courses and workshops, including some delivered entirely online, at both the undergraduate and post-graduate levels. She has led national and international efforts in crystallography education and training. Kantardjieff's activities led to her election to the United States National Committee for Crystallography, of which she is currently Vice Chair.

  Wayne Lukens (Chair)
Lawrence Berkeley National Laboratory, Chemical Sciences, 1 Cyclotron Rd., Berkeley, CA 94720
  Staff scientist in the Actinide Chemistry Group at Lawrence Berkeley National Laboratory. His research focuses mainly on the behavior of technetium in nuclear waste and nuclear wasteforms. In addition, his research examines electronic structure and bonding in actinide complexes. He has carried out EXAFS experiments at SSRL since 1992. Currently, he is using EXAFS and XANES to characterize the speciation of technetium in different nuclear wasteforms.

  Karen McFarlane Holman
Willamette University, Chemistry Department, 900 State St, Salem, OR 97301
  Associate Professor of Chemistry at Willamette University in Salem, OR. She has been a user at SSRL and the ALS since 1998. As a postdoc at LBNL (1998-2000), she worked with Mel Klein and VIttal Yachandra on SSRL Beam Lines 6-2, 7-3 and 9-3 in projects related to chloride in Photosystem II and sulfur in proteins. Another postdoctoral project in the Klein group involved designing and building the EXAFS endstation on Beam Line 9.3.1 at the ALS. Her current research projects use XANES to investigate fundamental mechanisms related to in vivo reactions of ruthenium-based anti-cancer drugs. Coming from Willamette University which is a liberal arts college, another goal of hers is to give undergraduate students the opportunity to travel to a national laboratory and collect their own data at a synchrotron source.
