Michael Peskin
Professor of Particle Physics and Astrophysics
BioI am a theoretical physicist interested in elementary particles and the fundamental interactions. My main research interests are:
* consequences of the "Standard Model of particle physics"
* precision study of the heaviest known elementary particles - the W and Z bosons, the top quark, and the Higgs boson - to search for clues to new fundamental interactions beyond the Standard Model
* models of such new interactions, especially models with composite or strongly interacting Higgs bosons
* models for the particle that composes the dark matter of the universe
I am the author of a leading theoretical textbook in this area, "An Introduction to Quantum Field Theory", with Daniel Schroeder. Recently, I have written another textbook that emphasizes our experimental knowledge, "Concepts of Elementary Particle Physics".

Piero Pianetta
Professor (Research) of Photon Science and of Electrical Engineering
BioPianetta's research is directed towards understanding how the atomic and electronic structure of semiconductor interfaces impacts device technology pertaining to advanced semiconductors and photocathodes. His research includes the development of new analytical tools for these studies based on the use of synchrotron radiation. These include the development of ultrasensitive methods to analyze trace impurities on the surface of silicon wafers at levels as low as 1e-6 monolayer (~1e8 atoms/cm2) and the use of various photoelectron spectroscopies (X-ray photoemission, NEXAFS, X-ray standing waves and photoelectron diffraction) to determine the bonding and atomic structure at the interface between silicon and different passivating layers. Recent projects include the development of high resolution (~30nm) x-ray spectromicroscopy with applications to energy materials such as Li batteries.

Helen Quinn
Professor of Particle Physics and Astrophysics, Emerita
BioHelen Quinn received her Ph.D in physics at Stanford in 1967. She has taught physics at both Harvard and Stanford. Dr. Quinn work as a particle physicist has been honored by the Dirac Medal (from the International Center for Theoretical Physics, Italy) and the Klein Medal (from The Swedish National Academy of Sciences and Stockholm University) as well as the Sakurai Prize (from the American Physical Society), the Compton medal (from the American Institute of Physics, awarded once every 4 years) and the 2018 Benjamin Franklin Medal for Physics (from the Franklin Institute). She is a member of the American Academy of Arts and Sciences, the National Academy of Science and the American Philosophical Society. She is a Fellow and former president of the American Physical Society. She is originally from Australia and is an Honorary Officer of the Order of Australia.
Dr. Quinn has been active in science education for some years, and since her retirement in 2010 this has been her major activity. She was a founding member of the Contemporary Physics Education Project (CPEP) which produced a well-known standard-model poster for schools in 1987 (see photo). She served as Chair of the US National Academy of Sciences Board on Science Education (BOSE) from 2009-2014. She was as a member of the BOSE study committee that developed the report “Taking Science to School” and chaired the committee for the “Framework for K-12 Science Education”, which is the basis of the Next Generation Science Standards (NGSS) and similar standards now adopted by about 30 states in the US, and has been influential internationally as well. She also contributed to follow-up NRC studies on assessment and implementation of NGSS. From 2015-2018 Helen served at the request of the President of Ecuador as a member of the “Comision Gestora” to help plan and guide the initial development of the National University of Education of Ecuador. -

John Louis Sarrao
Director of the SLAC National Accelerator Laboratory, Professor of Photon Science, Senior Fellow at the Precourt Institute for Energy and Professor, by courtesy, of Materials Science and Engineering
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 thousands of 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, and by courtesy, of materials science and engineering 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. -

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.
