Angelo Dragone
Associate Professor of Photon Science and, by courtesy, of Electrical Engineering
BioAngelo Dragone is an Associate Professor of Photon Science and Electrical Engineering (by courtesy). He has over 20 years of experience in the research and development of Instrumentation for Scientific experiments. He received his Ph.D. in Microelectronics from the Polytechnic University of Bari, Italy, for his research on mixed-signal readout architecture for radiation detectors, conducted at Brookhaven National Laboratory. He worked in the Instrumentation Division at Brookhaven National Laboratory from 2004, before joining SLAC National Accelerator Laboratory in 2008. Over the past 15 years, he has been designing radiation detectors, with a focus on innovative architectural solutions for state-of-the-art scientific instruments and sensor interfaces. These solutions have applications in photon science, particle physics, medical imaging, and national security. At SLAC, he focused his research on designing high frame rate, large dynamic range X-ray detectors for the Linac Coherent Light Source SLAC X-ray Free-electron Laser facility. Since 2012, he has held a management position as head of the Integrated Circuits Department within the Instrumentation Division of the Technology Innovation Directorate (TID) at SLAC. During the past three years, Dr. Dragone has been working on the strategic R&D planning for the SLAC X-ray detectors Initiative and leads, as Program Director, TID Detector R&D, and the applied Microelectronics program. Recently, he has been appointed as Deputy Associate Lab Director for TID strategy. His current research interests are on ultra-fast X-ray detector architectures for X-ray Free-Electron Lasers applications and developing efficient, scalable systems with "smart" real-time processing capabilities. More broadly, he is interested in understanding the fundamental performance limits of radiation detection systems.

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 and, by courtesy, of Chemistry
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.

Britt Hedman
Professor of Photon Science
BioBritt Hedman’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.
Britt 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. -
