Scott Acton
Scott Acton is currently the Wavefront Sensing and Controls Scientist for the James Webb Space Telescope, working at Ball Aerospace in Boulder, Colorado. In this role, he is building a team of people who have the responsibility of aligning JWST after it is launched in 2018. Prior to coming to Ball Aerospace, he was the AO engineer at the Keck Observatory, and worked with a different team of engineers to build the first AO systems on the world's largest telescopes. Prior to working at Keck, he was the PI of a solar Adaptive Optics project, at the Lockheed Missiles and Space Company (using the sun as an object instead of a point source.) He has recently taken on a contributing role in the task of phasing the 7 8.3 meter apertures for the Giant Magellan Telescope (GMT).

Kerri Cahoy

Kerri Cahoy is the Boeing Assistant Professor of Aeronautics and Astronautics at the Massachusetts Institute of Technology. Dr. Cahoy leads the MIT Wavefront Control Laboratory, part of the Space Systems Laboratory. Prof. Cahoy’s group has three research focus areas: Nanosatellites, Wavefront Control Systems, and Space Weather.

Michael Fitzgerald
Michael Fitzgerald is an Assistant Professor in the Infrared Laboratory of the Department of Physics and Astronomy at UCLA. His interests range from astronomical instrumentation, including coronagraphy and adaptive optics, to observational study of planet formation. In particular, he is interested in the application of high-contrast techniques to the direct imaging of extrasolar planets and circumstellar debris disks. In conjunction, he is also interested in the application of signal processing techniques to both adaptive optics systems and analysis of high-contrast imaging data.

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.

Dr. Max graduated from Radcliffe College and Princeton University. She was a Physicist at the Lawrence Livermore National Laboratory for many years, where she was founding director of the Institute of Geophysics and Planetary Physics at LLNL. Dr. Max's research interests include adaptive optics, laser guide stars, and their use for studies of active galactic nuclei – galaxies that have accreting black holes in their cores. Dr. Max was elected to the American Academy of Arts and Sciences in 2004 and the National Academy of Sciences in 2008. She is a Fellow of the American Physical Society and the American Association for the Advancement of Science. She was awarded the Ernest O.

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. Her research focuses on observing the cores of nearby late-stage gas-rich galaxy mergers, and the enhanced star formation and extreme black hole accretion that take place there. Adaptive optics is critical for her observations that resolve the nuclear regions where these two effects are competing for dominance. Anne has designed, facilitated and led labs at the AO Summer School, and in courses at UCSC and Hartnell College since 2009. Her work on these labs earned her a Certificate in Teaching Innovative Laboratory Experiences from the Institute for Scientist and Engineer Educators in 2010.
