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.

Wayne Lukens
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.

Stéphane Richard graduated from the University Joseph Fourier in Grenoble (France) where he completed his Ph.D. studying the principles underlying adaptation to extreme saline environments using X-ray protein crystallography as a tool. He then joined the team of Prof. Joseph P. Noel in the Structural Biology laboratory of the Salk Institute to study the biosynthesis of terpenoid natural products. Now part of the Jack H. Skirball Center for Chemical Biology and Proteomics, his interests concerns the biosynthesis of active polyketide/terpenoids hybrid natural products using a structure guided chemo-enzymatic approach for natural product derivatization to develop novel therapeutically relevant compounds.
