BioWhat were the first objects that formed in the Universe? Prof. Abel's group explores the first billion years of cosmic history using ab initio supercomputer calculations. He has shown from first principles that the very first luminous objects are very massive stars and has developed novel numerical algorithms using adaptive-mesh-refinement simulations that capture over 14 orders of magnitude in length and time scales. He currently continues his work on the first stars and first galaxies and their role in chemical enrichment and cosmological reionization. His group studies any of the first objects to form in the universe: first stars, first supernovae, first HII regions, first magnetic fields, first heavy elements, and so on. Most recently he is pioneering novel numerical algorithms to study collisionless fluids such as dark matter which makes up most of the mass in the Universe as well as astrophysical and terrestrial plasmas. He was the director of the Kavli Institute for Particle Astrophysics and Cosmology and Division Director at SLAC 2013-2018.
Associate Professor of Particle Physics and Astrophysics
BioI am an observational cosmologist, and an experimental physicist. I build ultra-low-noise detectors using superconducting and quantum sensing techniques, and use them in experiments and instrumentation for cosmology. I currently spend most of my time investigating the inflation paradigm of standard cosmology, using the cosmic microwave background (CMB). Recently, I've become interested in using the weak lensing of the CMB in conjunction with galaxy surveys to study the growth of large-scale structure in the universe.
I received my PhD in particle astrophysics from Caltech in 2012, working on direct detection of WIMP dark matter with the CDMS-II experiment. I then shifted my effort to searching for inflation with the CMB. I was a postdoctoral scholar at Stanford through 2015 before being appointed as a Wolfgang Panofsky Fellow at SLAC National Accelerator Laboratory. In 2017, I won a DOE Office of Science Early Career Award to work on new signal transduction and superconducting multiplexing techniques for next-generation CMB cameras. In 2020, I was appointed as a Lead Scientist at SLAC, and in 2023, I was appointed Associate Professor of Particle Physics and Astrophysics at Stanford and SLAC. I serve as CMB department head in the Fundamental Physics Directorate at SLAC. I also serve as scientific project manager for the bring up of SLAC's Detector Microfabrication Facility for the development of superconducting and quantum sensors and devices.

Professor of Particle Physics and Astrophysics, Emeritus
BioI have worked for more than 45 years in experimental particle physics, often in developing new kinds of electronics and instruments critical to the detectors that enable the physics experiments of interest. In 1965 through 1971, I was involved in the electron scattering program at SLAC. The deep inelastic experiments that discovered the scaling and point like structure in the nucleon, later interpreted as quarks, was my Ph.D. thesis. I then spent a year at CERN, mostly doing an experiment on minimum bias behavior of proton-proton scattering at the newly operating Intersecting Storage Rings. Despite intentions to stay longer at CERN, I was persuaded by Professor Richter to return to SLAC and join his SPEAR storage ring group. In the 1974 “November Revolution”, we discovered the and ’ particles, soon interpreted as bound states of charm-anti-charm quarks, which caused essentially complete acceptance of the quark model as real. Another critical discovery at SPEAR was the lepton, leading to the third family of the Standard Model.
Subsequently Professor Charles Baltay and I were co-spokesmen of the SLD, a comprehensive large detector for the SLAC Linear Collider (SLC), where we did Z physics, particularly polarization asymmetries possible because of the SLC polarized electron beam which led to a (correct) prediction of the Higgs mass, and precision b physics with a 300 MPixel CCD vertex detector.
I am now involved in the design of a detector for the International Linear Collider which may be built in Japan, which has led to substantial involvement in Si detector sensors and associated readout ASIC’s. I believe we have developed the first wafer scale sensors with on sensor traces leading to a relative small area “readout system on a chip” that delivers processed digital signals to a DAQ.
I also work on a search for neutrinoless double beta decay (02) in 136 Xe. The 02 experiment utilizes a liquid xenon TPC requiring ultra-low background materials, techniques, and locations, which was an education into rather different experimental techniques from collider detectors.
I am working on a new concept for an e+e- linear collider called C^3 for the Cool Copper Collider. The Cool Copper Collider (C3) is an advanced concept for a high energy e+e- linear collider. It is based on a new SLAC technology that dramatically improves efficiency and breakdown rate. C3 uses distributed power to each cavity from a common RF manifold and operates at cryogenic temperatures (LN2, ~80K). This makes it robust at high gradient: 120~MeV/m.
C3 is a promising option for a next-generation e+e- collider. It has the potential to reach energies of up to 1 TeV, which would allow it to study the properties of particles that are difficult to access with current experiments. C3 is also relatively affordable, which makes it a more viable option than some of the other proposed linear colliders.
Finally, these recent experiences have led to exploratory collaborative efforts in neuroscience, where we believe our SLAC expertise in sensors and electronics could be rather synergistic with Stanford efforts in tACs and in neural recording probes.

BioThe availability of low-cost but intermittent renewable electricity (e.g., derived from solar and wind) underscores the grand challenge to store and dispatch energy so that it is available when and where it is needed. Redox-active materials promise the efficient transformation between electrical, chemical, and thermal energy, and are at the heart of carbon-neutral energy cycles. Understanding design rules that govern materials chemistry and architecture holds the key towards rationally optimizing technologies such as batteries, fuel cells, electrolyzers, and novel thermodynamic cycles. Electrochemical and chemical reactions involved in these technologies span diverse length and time scales, ranging from Ångströms to meters and from picoseconds to years. As such, establishing a unified, predictive framework has been a major challenge. The central question unifying our research is: “can we understand and engineer redox reactions at the levels of electrons, ions, molecules, particles and devices using a bottom-up approach?” Our approach integrates novel synthesis, fabrication, characterization, modeling and analytics to understand molecular pathways and interfacial structure, and to bridge fundamentals to energy storage and conversion technologies by establishing new design rules.

Professor of Photon Science
BioHedman’s research program is focused on the development and applications of x-ray absorption and emission spectroscopies using synchrotron radiation, with a scientific emphasis primarily on study of the electronic and structural aspects of metal ion active sites in bioinorganic and biological systems. A common theme is to investigate how structure at molecular and macromolecular levels relates to function.
A major long-term focus has been the active site of the enzyme nitrogenase, and the various nitrogenase metal clusters, including elucidating the electronic and geometric structure of those that are formed and changed along their biosynthetic pathways. Other systems of systematic studies include iron-sulfur cluster containing enzymes, blue and multi-copper proteins, heme-copper oxidases, and iron-containing oxidases. Methods developments include x-ray absorption spectroscopy (edge and extended fine structure - or EXAFS), including the application of multiple-scattering analysis in EXAFS studies of metal clusters relevant to bioinorganic systems, the development of methodology for polarized single crystal x-ray absorption spectroscopy, and methodology and instrumentation development for soft- through hard-energy XAS.
Hedman received her B.S and B.A. in Chemistry, M.Sc. in Inorganic Chemistry, and Ph.D. in Chemistry from the University of Umeå, Sweden. She was Assistant Professor (equivalent) in Inorganic Chemistry at the University of Umeå before coming to Stanford, initially as Senior Academic Scientific Staff, followed by appointed as Professor (Research) in 2002, and Professor of Photon Science in 2007.

BioCombining inorganic, biophysical and structural chemistry, Professor Keith Hodgson investigates how structure at molecular and macromolecular levels relates to function. Studies in the Hodgson lab have pioneered the use of synchrotron x-radiation to probe the electronic and structural environment of biomolecules. Recent efforts focus on the applications of x-ray diffraction, scattering and absorption spectroscopy to examine metalloproteins that are important in Earth’s biosphere, such as those that convert nitrogen to ammonia or methane to methanol.
Keith O. Hodgson was born in Virginia in 1947. He studied chemistry at the University of Virginia (B.S. 1969) and University of California, Berkeley (Ph.D. 1972), with a postdoctoral year at the ETH in Zurich. He joined the Stanford Chemistry Department faculty in 1973, starting up a program of fundamental research into the use of x-rays to study chemical and biological structure that made use of the unique capabilities of the Stanford Synchrotron Radiation Lightsource (SSRL). His lab carried out pioneering x-ray absorption and x-ray crystallographic studies of proteins, laying the foundation for a new field now in broad use worldwide. In the early eighties, he began development of one of the world's first synchrotron-based structural molecular biology research and user programs, centered at SSRL. He served as SSRL Director from 1998 to 2005, and SLAC National Accelerator Laboratory (SLAC) Deputy Director (2005-2007) and Associate Laboratory Director for Photon Science (2007-2011).
Today the Hodgson research group investigates how molecular structure at different organizational levels relates to biological and chemical function, using a variety of x-ray absorption, diffraction and scattering techniques. Typical of these molecular structural studies are investigations of metal ions as active sites of biomolecules. His research group develops and utilizes techniques such as x-ray absorption and emission spectroscopy (XAS and XES) to study the electronic and metrical details of a given metal ion in the biomolecule under a variety of natural conditions.
A major area of focus over many years, the active site of the enzyme nitrogenase is responsible for conversion of atmospheric di-nitrogen to ammonia. Using XAS studies at the S, Fe and Mo edge, the Hodgson group has worked to understand the electronic structure as a function of redox in this cluster. They have developed new methods to study long distances in the cluster within and outside the protein. Studies are ongoing to learn how this cluster functions during catalysis and interacts with substrates and inhibitors. Other components of the protein are also under active study.
Additional projects include the study of iron in dioxygen activation and oxidation within the binuclear iron-containing enzyme methane monooxygenase and in cytochrome oxidase. Lab members are also investigating the role of copper in electron transport and in dioxygen activation. Other studies include the electronic structure of iron-sulfur clusters in models and enzymes.
The research group is also focusing on using the next generation of x-ray light sources, the free electron laser. Such a light source, called the LCLS, is also located at SLAC. They are also developing new approaches using x-ray free electron laser radiation to image noncrystalline biomolecules and study chemical reactivity on ultrafast time scales.
