Professor Chris Impey interviews Dr. Buddy Martin, Chief Polishing Scientist at the Steward Observatory Mirror Lab. Dr. Martin is the Project Scientist for Mirror Polishing at the Richard F. Caris Mirror Lab. He leads the development of fabrication and testing for large optics, including the 8.4 m segments of the Giant Magellan Telescope. Previous manufacturing achievements include the two 8.4 m primary mirrors of the Large Binocular Telescope, the 8.4 m combined primary and tertiary mirror for the Large Synoptic Survey Telescope, and thin deformable secondary mirrors for the LBT. Buddy has a Ph. D. in physics from Cambridge University and has been at Steward Observatory since 1986. He worked in radio astronomy before moving up to manufacturing optics.
