Mike Dunne
Professor of Photon Science
Current Research and Scholarly InterestsThe Linac Coherent Light Source (LCLS) is the world's first X-Ray Free Electron Laser. It represents a revolution in x-ray science. The x-rays produced by LCLS are a billion times brighter than can be produced by conventional sources, such as a synchrotron, and are delivered in ultrafast bursts- typically a few tens of femtoseconds (10^-15 seconds). This opens up transformational opportunities for the study of structural biology, quantum materials, ultrafast chemistry, and novel states of matter

Kelly Gaffney
Professor of Photon Science
Current Research and Scholarly InterestsThe research team Professor Gaffney leads focuses on time resolved studies of chemical reactions. Recent advances in ultrafast x-ray lasers, like the LCLS at SLAC National Accelerator Laboratory, enable chemical reactions to be observed on the natural time and length scales of the chemical bond – femtoseconds and Ångströms. The knowledge gained from x-ray and optical laser studies will be used to spark new approaches to photo-catalysis and chemical synthesis.

Spencer Gessner
Assistant Professor of Particle Physics and Astrophysics
BioDr. Spencer Gessner is an Assistant Professor of Particle Physics and Astrophysics at SLAC National Accelerator Laboratory and Stanford University. Dr. Gessner was previously a Staff Scientist at SLAC researching plasma wakefield acceleration at FACET-II, and a Fellow at CERN on the AWAKE proton beam-driven plasma acceleration experiment. Dr. Gessner earned a Ph.D. from Stanford University studying the acceleration of positron beams in plasma. Dr. Gessner is currently coordinating the US 10 TeV Wakefield Collider Design Study and is broadly involved in research on future colliders from Higgs Factories to future Energy Frontier machines.

Britt Hedman
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. -
