John Louis Sarrao
Director of the SLAC National Accelerator Laboratory, Professor of Photon Science and Senior Fellow at the Precourt Institute for Energy
BioJohn Sarrao became SLAC National Accelerator Laboratory’s sixth director in October 2023. The lab’s ~2,000 staff advance the frontiers of science by exploring how the universe works at the biggest, smallest, and fastest scales and invent powerful tools used by scientists around the globe. SLAC’s research helps solve real-world problems and advances the interests of the nation. SLAC is operated by Stanford University for the U.S. Department of Energy’s Office of Science. It is home to three Office of Science national user facilities: the Linac Coherent Light Source (LCLS), the world’s most powerful X-ray laser; the Stanford Synchrotron Radiation Lightsource (SSRL); and the Facility for Advanced Accelerator Experimental Tests, (FACET-II). SLAC hosts nearly 1,000 users each year and manages an annual budget of ~$700M. In addition to his role as lab director, John is a professor of photon science at Stanford University, a senior fellow at Stanford’s Precourt Institute, and dean of SLAC faculty.
John came to SLAC from Los Alamos National Laboratory (LANL) in New Mexico, where he served as the deputy director for science, technology, and engineering. In that role, he led multiple directorates, including chemistry, earth and life sciences, global security, physical sciences, and simulation and computation. He also stewarded technology transitions and served as LANL’s chief research officer in support of its national security mission. Before becoming deputy director, he served as associate director for theory, simulation, and computation and division leader for materials physics and applications at LANL.
John’s scientific research focus is superconductivity in materials. He studies the synthesis and characterization of correlated electron systems, especially actinide materials. He won the 2013 Department of Energy’s E.O. Lawrence Award and is a fellow of the American Association for the Advancement of Science, the American Physical Society, and LANL. John received his PhD and master’s degree in physics from the University of California, Los Angeles, and a bachelor’s degree in physics from Stanford University. -
Philip Schuster
Professor of Particle Physics and Astrophysics
BioProfessor Schuster is a theoretical physicist focused on identifying dark matter and its properties, developing concepts for new experimental tests of physics beyond the Standard Model, and studying novel theories of long-range forces. He is also directly involved in several experimental efforts as co-spokesperson for APEX, a founding member and physics coordinator for LDMX, and as a founding member of HPS.
Prospective graduate students interested in research rotations should contact Professor Schuster directly. Recent research directions include new ideas to detect axions, milli-charge dark matter, the use of novel accelerator experiments to search for light WIMP-like dark matter, and generalizations of gauge theories that include massless particles with continuous spin. Publications are listed on INSPIRE.
Professor Schuster is also chair of the Particle Physics & Astrophysics department at Stanford’s SLAC National Accelerator Laboratory. -
Georgios Skiniotis
Professor of Molecular and Cellular Physiology, of Structural Biology and of Photon Science
BioThe Skiniotis laboratory seeks to resolve structural and mechanistic questions underlying biological processes that are central to cellular physiology. Our investigations employ primarily cryo-electron microscopy (cryoEM) and 3D reconstruction techniques complemented by biochemistry, biophysics and simulation methods to obtain a dynamic view into the macromolecular complexes carrying out these processes. The main theme in the lab is the structural biology of cell surface receptors that mediate intracellular signaling and communication. Our current main focus is the exploration of the mechanisms responsible for transmembrane signal instigation in cytokine receptors and G protein coupled receptor (GPCR) complexes.

Edward I. Solomon
Monroe E. Spaght Professor of Chemistry and Professor of Photon Science
On Leave from 04/01/2024 To 06/30/2024Current Research and Scholarly InterestsProf. Solomon's work spans physical-inorganic, bioinorganic, and theoretical-inorganic chemistry, focusing on spectroscopic elucidation of the electronic structure of transition metal complexes and its contribution to reactivity. He has advanced our understanding of metal sites involved in electron transfer, copper sites involved in O2 binding, activation and reduction to water, structure/function correlations over non-heme iron enzymes, and correlation of biological to heterogeneous catalysis.

Summary of Scientific Work:
My early scientific research focused on the development of x-ray based surface techniques, especially surface EXAFS and NEXAFS, and their use for the determination of the geometric arrangement and bonding of atoms, molecules and thin organic films on surfaces. This work is summarized in my review article “SEXAFS: Everything you always wanted to know about SEXAFS but were afraid to ask” (in X-Ray Absorption: Principles, Applications, Techniques of EXAFS, SEXAFS and XANES, Edits. D. Koningsberger and R. Prins, Wiley, 1988) and my 1992 book “NEXAFS Spectroscopy” (Springer).
My later research focused on magnetic materials and phenomena, in particular the study of magnetic thin films, interfaces and nanostructures, and their ultrafast dynamics by use of forefront x-ray techniques. This work forms the foundation of my 2006 book (with H. Siegmann) entitled “Magnetism: From Fundamentals to Nanoscale Dynamics” (Springer).
With the advent of x-ray free electron lasers (XFELs) around 2010 my research increasingly focused on the description of x-rays and their interactions with matter within modern quantum optics, leading to my 2023 book “The Nature of X-Rays and their Interactions with Matter”.
In total I have written 3 books, 10 review articles in the form of book chapters and about 250 scientific Journal publications. I hold 5 patents and have given more than 150 invited talks at international scientific conferences, about 100 colloquia at Universities and Scientific Research Institutions, and 3 public lectures on the topic of magnetism and x-ray free electron lasers.
