Dr. Christopher T. Parzyck
Postdoctoral Scholar, Photon Science, SLAC
BioMy research interests lie at the intersection of materials science and condensed matter physics. I work on thin film synthesis of oxide and metal systems by molecular-beam epitaxy (MBE). Applications range from answering fundamental physics questions about high temperature superconductivity to developing practical synthesis routines and new materials for next generation electron sources. In addition, I work on projects involving spectroscopic probes of thin film systems, including angle-resolved photoemission spectroscopy (ARPES) and resonant soft x-ray scattering (RSXS) measurements.

BioMy current research focuses on the design of catalytic materials. I have studied atomistic phenomena on catalytic surfaces to develop materials with improved catalytic capability under the philosophy of rational design. To achieve this goal, I use computational approaches, e.g., first-principles calculations and artificial intelligence (AI). Applications include heterogeneous catalysis for exhaust emission control, hydrogen production, and utilization of emission gas to realize carbon neutralization.

MANUEL RAFAEL VEJAR
Postdoctoral Scholar, Photon Science, SLAC
BioManuel (Manny) Vejar is a postdoctoral scholar at SLAC National Accelerator Laboratory, specializing in synchrotron X-ray fluorescence imaging and X-ray absorption spectroscopy to study environmental and rhizosphere biogeochemistry at the Stanford Synchrotron Radiation Lightsource.
He received his Ph.D. in the Civil & Environmental Engineering & Earth Sciences department at the University of Notre Dame in 2024. His doctoral research focused on the impacts of iron-oxide mineral complexity on the fate and transport of plutonium in nuclear waste repository and/or legacy environmental contamination settings. Specifically, he studied the influence of Al-substitution in iron (oxyhydr)oxide minerals on the redox and speciation behavior of plutonium at the mineral-water interface, employing M4-edge high-energy resolution fluorescence-detected X-ray absorption near-edge structure (HERFD-XANES) spectroscopy to determine the oxidation state and L3-edge extended X-ray absorption fine-structure (EXAFS) spectroscopy to determine coordination environment of the plutonium associated with these minerals.
He has over 7 years of experience with synchrotron techniques (micro-X-ray fluorescence imaging, XANES, and EXAFS), and their applications to study metal(loid)s in environmental systems. During his career, Manny has conducted work at the Stanford Synchrotron Radiation Lightsource, the Advanced Photon Source, and the European Synchrotron Radiation Facility, while collaborating with Chapman University, the Institute of Resource Ecology at the Helmholtz-Zentrum Dresden-Rossendorf, and more recently Oak Ridge, Pacific Northwest, and Livermore national labs, and the University of Puerto Rico in Mayaguez. Prior to his Ph.D. at the University of Notre Dame, Manny obtained his B.Sc. in Geology from the California State Polytechnic University, Pomona. -

Zisheng Zhang
Postdoctoral Scholar, Photon Science, SLAC
BioZisheng Zhang is a Stanford Energy Fellow at SUNCAT Center for Interface Science and Catalysis, co-hosted by Dr. Frank Abild-Pedersen (SLAC) and Prof. Thomas Jaramillo (Chemical Engineering). He is interested in physics-steered, complexity-driven, and AI-accelerated simulations for understanding, design, and discovery of novel functional catalysts, materials, molecules, and interfaces.
ZZ grew up in Wuhan and received undergraduate training in both experimental and computational chemistry at South University of Science and Technology of China (with Prof. Jun Li) and University of California, Los Angeles (with Prof. Anastassia N. Alexandrova). He then stayed at UCLA and obtained his M.Sc. and Ph.D. in Theoretical and Computational Chemistry. During PhD study, he did research internship at Argonne National Lab in 2022 with Dr. Maria Chan. -
