SSRLUO 2013-2014 Executive Committee Members

Jordi Cabana
University of Illinois at Chicago, IL 60607
Jordi Cabana recently joined the University of Illinois in 2013. Prior to that time, Jordi was a Research Scientist at LBNL. He moved to the US in 2005 to join Prof. Clare P. Grey’s group at the State University of New York at Stony Brook as a Postdoctoral Research Associate, after completing his Ph.D. in Materials Science at the Institute for Materials Science of Barcelona in Spain in 2004. Jordi's research work focuses on the design and characterization of materials for electrochemical energy storage, with emphasis placed on the understanding of the fundamental mechanisms of reaction. He has extensively used long range (X-ray and neutron diffraction) and short range (X-ray absorption spectroscopy, Nuclear Magnetic Resonance) characterization techniques, both in situ and ex situ, to probe crystal and electronic structure features of a variety of materials. He has performed some of these experiments at SSRL, ALS and NSLS. More recently, Jordi has leveraged technical developments in nanoscale chemical imaging to investigate kinetic and thermodynamic factors that control redox phase transformations in single particle and their ensembles.
Stanford University, Stanford, CA  94025
Justin Chartron is a postdoctoral fellow working with Judith Frydman at Stanford University. His experience in protein crystallography began in 2001 as a high school intern with Dave Stout at The Scripps Research Institute where he crystallized several proteins whose structures were determined using data collected at SSRL. He continued working with Dave as an undergraduate at UC San Diego, and solved his first structure using anomalous scattering at BL9-2. He went to Caltech for graduate school fully intending to use the soon-to-be commissioned BL12-2. Working with Bil Clemons, he had the pleasure of watching the Molecular Observatory mature, and he has used its resources to determine numerous structures of proteins involved in membrane targeting. He complemented high resolution structures with small angle X-ray scattering data at BL4-2. In addition to SSRL, he uses ALS and APS. As a postdoc, he has initiated several structural projects in the Frydman group, which had not previously performed crystallography. He has trained several group members, and in recent months has used SSRL to determine structures of molecular machines involved in protein folding. His research focuses on the mechanisms discriminating alternative nascent protein fates.
