Joshua J. Turner
Lead Scientist, SLAC National Accelerator Laboratory
BioJoshua Turner is a lead scientist at the Stanford Institute for Materials and Energy Sciences, a joint institute between Stanford University and SLAC, as well as at the Linac Coherent Light Source, the world’s first x-ray free electron laser (XFEL) based at SLAC.
He received both a BS in Physics and a BA in Mathematics from UC Santa Barbara, a MA in Physics from Boston University, and a PhD in Physics from the University of Oregon. He moved to Stony Brook University, NY to work as a postdoctoral fellow, lecturer, and then adjunct assistant professor, before coming to Stanford.
Turner is a leader in ultra-fast x-ray studies, which he has applied to an array of scientific fields, from chemistry and materials physics to the study of plasmas found in large planets and hot astrophysical objects. His most recent work focuses on new modes of the XFEL which can be used to examine subtle fluctuations in materials using short, coherent x-ray pulses on new energy scales. This will advance the frontier in quantum materials through the observation of novel types of order found in exotic systems such as topological magnets, unconventional superconductors, and strongly spin-orbit coupled Mott insulators.
He is the recipient of the Department of Energy’s Early Career Award, a prestigious award granted to further the individual research programs of outstanding scientists with demonstrated successful research activities and potential for solving important problems to the U. S. government. He has published over 100 scientific articles with one-third of them in high-profile journals. -
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. -
Caterina Vernieri
Assistant Professor of Particle Physics and Astrophysics
BioCaterina Vernieri received her PhD on the CMS experiment from the Scuola Normale Superiore in Pisa, Italy, in 2014 and then moved to Chicago for a postdoctoral fellowship at the Fermi National Accelerator Laboratory. She joined SLAC in 2018 as a Panofsky Fellow and moved to the ATLAS experiment, and in 2022 she became Assistant Professor.
Throughout this time, she has been devoted to studying the Higgs boson using data from the LHC. She co-led the group in the CMS experiment studying the Higgs decay to b quarks at the time that this important decay process was finally discovered in the data. At SLAC, Caterina is working with the ATLAS experiment at the LHC with a focus on Higgs physics. She is responsible for the integration activities at SLAC of the new ATLAS Pixel Inner Tracker detector.
She was also co-convener of the group on Higgs boson properties in the US national study of the future of particle physics. -
Johannes Voss
Staff Scientist, SLAC National Accelerator Laboratory
BioJohannes Voss is Staff Scientist at the SUNCAT Center for Interface Science and Catalysis at SLAC National Accelerator Laboratory. He leads a research team focused on the atomic-level understanding and computational design of systems of relevance for renewable storage and conversion of energy. The team employs machine learning approaches to improve the predictive power of super computer simulations for chemical reactions with emphasis on heterogeneous catalysis.
