SSRL Users’ Organization Ballot The SSRL Users’ Organization Executive Committee represents the scientific user community to the SSRL administration, the SSRL Science Policy Board and the DOE in matters of operation, policy and improvements. Members serve a two-year term. Members are elected by the SSRL user community via majority vote. Present Committee - Remaining Members Name Institution Field Inst.

He and his coworkers use synchrotron radiation to study phase transitions and structural transformations in nanocrystals. Corwin Booth: A staff scientist in the Actinide Chemistry Group at LBNL. Conducts x-ray absorption investigations on a wide variety of materials with interesting electronic, chemical, or structural properties. These include transition-metal oxides, intermetallic compounds (esp. heavy fermions), borides as well as materials that relate to environmental concerns, such as waste-form glasses, actinide species in solution, and other materials containing transuranic elements. Susan Carroll: Research expertise is experimental and field investigations of equilibrium- and kinetically-controlled water-rock interactions. For the past 7 years she has used synchrotron-based X-ray absorption spectroscopy to determine the local coordination and bonding of heavy metals to mine drainage and estuary sediments and of Sr to pure minerals suspensions. Howard Einspahr: Leads a macromolecular crystallography group supporting drug design for Bristol-Myers Squibb. Uses synchrotron radiation for structure studies, including determinations of new protein structures and of structures of complexes of proteins with novel ligands. Kim Hayes: An Associate Professor of Environmental Engineering in the Department of Civil and Environmental Engineering at the University of Michigan with a specialty in environmental surface and interfacial chemistry. Performing work at SSRL since 1984, to characterize metal ion sorption complexes under environmentally relevant conditions in order to improve our ability to model and predict sorption behavior of radionuclides and hazardous metals in colloidal and soil systems. Nancy Hess: Actinide and Trace Metal Geochemistry Group, Biogeochemistry Department, at PNNL. Her research focus is environmental geochemistry and radiation effects in waste materials. She has specialized in the speciation of actinides and trace metals and the structural investigation of solid phases over a range of length scales using molecular spectroscopic methods such as XAS, diffuse x-ray scattering, vibrational and fluorescence spectroscopies. Todd Hufnagel: An assistant professor of materials science and engineering at Johns Hopkins University. His research concerns the structure, phase transformations, and properties of amorphous metallic alloys. He performs a variety of experiments at SSRL, including small-angle x-ray scattering, anomalous scattering and EXAFS. George Meitzner: Is the President of Edge Analytical, Inc. and a consultant to academic and industrial groups. He measures or assists in measurement of x-ray absorption spectra from a wide variety of materials, and analyzes spectra regardless of having participated in the measurement. Clients are encouraged to bring their work to SSRL because superior experimental support provides efficient learning and a high chance of success. Satish Myneni: Scientist at the Lawrence Berkeley National Laboratory, and conducting hard and soft X-ray spectroscopy on geochemical systems. Marilyn Olmstead: Is the Director of the small-molecule X-ray crystallographic facility in the Department of Chemistry at UC Davis. We do about 400 crystal structures a year. Some of these structures are not routine and not that "small." I use synchrotron to study higher fullerenes and endohedral fullerenes (those containing substances inside, e.g. Li, Sc, Er, and La) because the crystals are typically quite small and poorly diffracting. George Redden: Activity at SSRL involves a study of surface coordination of uranyl on iron oxides in the presence of chelating ligands. The ligands are currently citric acid and EDTA with the expectation to extend the work to a suite of microbial chelating compounds. A particular interest is in the thermodynamics of multidentate complexation on mineral surfaces. Stuart Stock: His area is materials science, specifically in diffraction. Areas of research are high resolution x-ray imaging (x-ray diffraction topography and x-ray computed tomography) and microbeam diffraction. 1999/2000 SSRLUO-EC Ballot
