Professor, Astronomy & Astrophysics
My research deals with the design and construction of high-performance optics for astronomy. My pioneering collimator and camera designs for spectrographs such as COSMIC at Palomar, HECTOCHELLE and BINOSPEC on MMT, IMACS on Magellan I, and LRIS, HIRES, ESI and DEIMOS on Keck 1 and Keck 2 are key to modern quantitative investigations of the Universe by many optical astronomers. MOSFIRE, a fully cryogenic near-ir spectrograph for KECK 1, is my latest design. It will be the most powerful instrument of its kind in the world when it is commissioned early in 2011.
