Steve KeyInterview with Steve Key

Steve Key graduated with honors from California State Polytechnic University of Pomona on June 11, 2005, with a B.S. degree in architecture. The subject of Steve’s thesis was the support facility for the Thirty Meter Telescope (TMT). He is currently working toward his architectural license in the State of California, and intends to continue his education in graduate school.

At the request of TMT staff, Steve answered a few questions about his thesis and his unusual perspective on the project.


Interview with David Crampton

David CramptonDavid Crampton is the instruments group leader for the Thirty Meter Telescope project, and the head of the instrumentation group at the Dominion Astrophysical Observatory/Herzberg Institute of Astrophysics (HIA) in Victoria, Canada. In his capacity for TMT, David is leading the planning and management of the instrumentation activity, in close partnership with Brent Ellerbroek, who is playing a similar role for adaptive optics.

David has been the Principal Investigator or had major involvement in the production of several multi-object spectrographs and adaptive optic systems for the Canada-France-Hawaii Telescope (CFHT) and the Gemini Observatory, and has been a member of the science teams for the James Webb Space Telescope (JWST) NIRCAM and NIRSPEC instruments. His scientific research focuses on the high-redshift universe, principally through studies of extremely high-redshift galaxies, quasars and gravitational lenses. A few decades ago, he was a co-discoverer of the first black hole in a galaxy outside our own, a discovery that helped establish the reality of black holes.

David spoke recently with Doug Isbell of NOAO public affairs about the state of the TMT instrumentation program, and its greatest challenges.


Interview with Jerry Nelson

Jerry NelsonAstronomer Jerry Nelson of the University of California Observatories/Lick Observatory at UC Santa Cruz is the Project Scientist for the Thirty Meter Telescope.

Jerry brings great experience as the principal designer and project scientist for the world’s largest optical telescopes, the twin W. M. Keck telescopes on Mauna Kea, Hawaii, to his job with TMT, including recent work on Keck’s state-of-the-art adaptive optics systems.

Jerry received his B.S. in physics from the California Institute of Technology and his Ph.D. in elementary particle physics from UC Berkeley. He has earned numerous honors for his work on the Keck Telescopes. Jerry spoke recently with Warren Skidmore about the challenges and opportunities of the TMT project.
