	Juana Acrivos CSU San Jose, Chemistry, 1 Washington Square, SanJose, CA 95192-0101
	Juana Acrivos has done experiments at SSRL since 1978. She is a chemist at SJSU (Professor). Her students first work at SSRL (Alan Robertson, Kevin Hathaway) showed how metal (Rb and Ba) in ammonia solutions change valence from 0 (in metallic solutions) to ionic values as the dilution is increased. The dynamics of intercalation chemistry was investigated in the '80s for TaS2 exposed to N2H4 in the beam (John Reynolds, Stuart S P Parkin). Battery action was revealed by investigating the Se edge shifts in (C(graphite|Cx(H2SeO4)|Cx<N2H4) (Adrienne Fishgrund). The late '90s revealed the dynamics of phase transitions in superconducting cuprates near the BaL3- edge. Thaddeus Norman uncovered phase transition phenomena in the NiS2-xSex system by Se and Ni XAS. Now together with Maria Angeles Navacerrada (Complutense University in Madrid). She has uncovered novel periodic lattice distortions in nano-scale films of YBCO at room temperature by XRD.

	Joy Andrews (Chair) California State University East Bay, Chemistry, 25800 Carlos Bee Blvd., Hayward, CA 94542
	Associate Professor of Chemistry at California State University East Bay, has had 10 years' experience at SSRL, first with University of California Berkeley from 1992-1996, and continuing with research in the remediation of heavy metals in the environment with plants and novel materials. Her work on safety and other committees at LBNL and CSUEB will inspire her to help shape the professional and innovative environment at SSRL.

	Alex Bell University of California, Berkeley, ChemicalEngineering, 107 Gilman Hall, Berkeley, CA 94720-1462
	Professor, Department of Chemical Engineering, University of California, Berkeley (1967-present). His research is on the relationships between the local composition and structures of catalytically active centers and the activity and selectivity of these centers. He uses the facilities as SSRL to obtain EXAFS and XANES data to identify the local structure of metal cations exchanged into zeolites and supported metal oxo units. Quantum chemical calculations of proposed structures are carried out and these are used to produce simulated radial structure functions for comparison with those obtained from experimental data.

	Linda Brinen University of California San Francisco, Sandler Center, QB3, 1700 4th St, Box 2500, San Francisco, CA 94143-2550
	Assistant Adj. Professor of Cellular and Molecular Pharmacology at the University of California, San Francisco, has made active use of SSRL's macromolecular crystallography resources since 1994 including two years of employment at SSRL within the Joint Center for Structural Genomics. She is the director of X-ray Crystallography at the Sandler Center for Basic Parasitic Disease research at UCSF. The research in her laboratory centers around two main areas: the structure, function, and designed regulation of proteolytic enzymes involved in parasitic infection and in allergic response.

	Michael Brzustowicz Stanford University, School of Medicine, 318 E Campus Dr., Stanford,CA 94305-5432
	Physicist studying the structure and function of biological membranes. Currently a post doc at Stanford University, School of Medicine, Mike has traveled the continent in search of beamlines suited for biomembranes work. Sadly, few places offer the specialized setup needed for X-ray scattering/diffraction studies of lipid bilayers, vesicles and lipid/protein complexes. Mike is particularly interested in 1) sharing his knowledge on "tweaking" existing beamlines for membranes studies 2) soliciting membrane researchers, directly, to utilize the superior resources at SSRL and 3) establishing a nationwide beamline control system, for biomembranes experiments, based on that of SSRL's macromolecular crystallography beamlines.

	Jesse Guzman University of California at Santa Cruz, Physics, 1313 High St., Santa Cruz, CA 95060
	Second year UCSC graduate student doing EXAFS studies with the Bud Bridges group. His undergraduate studies at the University of Michigan with a BS in physics allowed him close access to APS. Working at APS sector 7 from 2001 until 2004 exposed him to a variety of x-ray science techniques such as time-resolved x-ray diffraction, coherent Bragg rod x-ray diffraction of thin films, and beam-line studies. Time resolved EXAFS, EXAFS on single crystals (including transmission through manganite single crystals), and developing new x-ray techniques currently dominate his research interests.

	Zsuzsa Hamburger Stanford University, Department of Structural Biology, 299 Campus Dr. West, Stanford, CA 94305
	Postdoctoral fellow in Dr. William Weis' laboratory at the Department of Structural Biology at Stanford University School of Medicine. She was trained as a protein crystallographer in Pamela Bjorkman's lab at Caltech, where she solved the three-dimensional crystal structure of the bacterial integrin-binding protein, invasin. Currently, she is working on determining the crystal structures of several proteins involved in exocytosis.

	Christopher S. Kim (Vice-Chair) Chapman University, Physical Sciences, One University Ave., Orange, CA 92866
	Assistant Professor in the Department of Physical Sciences at Chapman University in Southern California. He conducted his graduate work at Stanford University under Gordon Brown and continued his research as a post-doc at Lawrence Berkeley National Laboratory with Glenn Waychunas. He has been a user at SSRL since 1996 and has also conducted research at the ALS and APS. Currently, he is studying trends in the speciation, concentration, and distribution of heavy metals in mine wastes as well as the mechanisms and extent of metal uptake and (co-)precipitation with iron oxyhydroxide nanoparticles. Chris is also involved in increasing the exposure of undergraduate students to national synchrotron facilities.

	Robert Szilagyi Montana State University, Chemistry and Biochemistry, 223 Gaines Hall, Bozeman, MT 59715
	Assistant Professor of Chemistry at Montana State University-Bozeman. His research interest focuses on bioinorganic, organometallic, and computational application of synchrotron radiation. He has five years of experience in XAS at various beamlines of SSRL and ALS. He uses NEXAS and EXAFS techniques in close correlation with theoretical calculations to investigate the relationships between chemical reactivity and electronic and geometric structures of bioinorganic active sites and biomimetic compounds, such as iron-sulfur clusters, S-nitrosated thiolates, as well as, tungsten, molybdenum, and palladium containing homogeneous catalysts. His motivation to be part of the SSRLUOEC is to provide a representation for junior faculty, to increase graduate and undergraduate student training, and to develop a spectral database for the community of synchrotron radiation users.
