David Fried
Dr. Fried, who received his Ph.D. in physics from Rutgers University in 1962, is perhaps best known in the adaptive optics community for his work defining the quantity generally denoted by the notation r0 — which he refers to as the effective coherence diameter, and to which Prof. Francois Roddier many years ago attached the name “Fried’s parameter.” Dr. Fried’s first paper on the optical effects of atmospheric turbulence was published in 1965. Then for almost a decade following, his many publications constituted almost the entirety of the work in the US analyzing the optical effects of atmospheric turbulence. With the start of the development of adaptive optics systems in the early part of the 1970’s Dr. Fried was a principle contributor to the analytic foundations of this subject area. His analysis of the effects of atmospheric turbulence when using a laser guide-star, showing that for a high but achievable back-scatter altitude the so called “focus anisoplanatism” effect was tolerably small for interesting size apertures, played a major part in the decision to fund the work that established the laser guide-star approach to adaptive optics. He designed the first experiment to test the the laser guide-star approach to adaptive optics, and directed that experiment’s data analysis — establishing the soundness of the laser guide-star concept.
Donald Gavel
Donald Gavel is Director of the Laboratory for Adaptive Optics (LAO) at the University of California, Santa Cruz and is an Associate Director of the Center for Adaptive Optics, leading the theme area for development of adaptive optics on large astronomical telescopes. He is actively involved on design teams for the Gemini Planet Imager, Thirty Meter Telescope, and Keck Next Generation Adaptive Optics projects.  Dr. Gavel spent a number of years developing the Lick Observatory Laser Guidestar Adaptive Optics system and participated in the development of the Keck Laser Guidestar System. Prior to his appointment at UCO/Lick, he worked in the adaptive optics group at the Lawrence Livermore National Laboratory developing AO systems for horizontal path coherent imaging and communications and on various AO systems for vision science application.
Olivier Guyon
Olivier Guyon graduated from University of Paris 6 in 2002 (Ph.D. research topic: wide field interferometry), and then joined Subaru Telescope's Adaptive Optics group. He now shares his time between Subaru Telescope and the University of Arizona, where he is associate professor in the Center for Astronomical Adaptive Optics. His research interests include quasar host galaxies and exoplanets.  Guyon has been developing new concepts for wavefront control and coronagraphy to enable direct imaging of exoplanets and disks from ground-based and space telescopes. He is now leading a small team to build a coronagraphic extreme-AO system for the Subaru Telescope, and also works with NASA scientists and engineers to plan a future space-based exoplanet imaging mission. He was awarded the Presidential Early Career Award for Scientists and Engineers (PECASE) by the office of the president of the United States in 2006 and the MacArthur fellowship in 2012.

Anne Medling
Anne Medling is a postdoc in astronomy at the Australian National University. She received her Ph.D. in Astrophysics at the University of California, Santa Cruz.
