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. |

nanoparticles. Chris is also involved in increasing opportunities for
undergraduate students to conduct research at national synchrotron facilities. |

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. |
