I am a senior research astronomer and member of the professional staff at the California Institute of Technology. Most of my time is devoted to the Spitzer Space Telescope mission and the Palomar Transient Factory. I specialize in pan-chromatic studies of star-formation and AGN, with an emphasis on the evolution of galaxies and quasars in the local universe through galaxy mergers. Most of my work involves advanced imaging techniques including adaptive optics, and is mostly centered in the infrared.

I was born in upstate New York, grew up in Houston, and have lived most of my life in Pasadena, California. I think of Honolulu as home, and this as a prolonged exile. On most days I can be found over in the Keith-Spalding building, office #205, in the hallway across from the elevators.

The images above represent the universe going outwards. At left is me on the Tibetan plateau. To my left (your right!) is Saturn in the near-infrared taken from the UH 88-inch telescope. Next is the Crab Nebulae in the optical, taken by the Palomar Transient Factory. This is followed by M101 (the Pinwheel Galaxy) and Arp 271 (an interacting pair of galaxies) also from PTF. Next on the right in blue is the ultraluminous infrared galaxy Arp 220 as observed by the 88-inch. The black-and-white galaxies in the background lie at high redshift in the Spitzer/IRAC Dark Field and were observed with the ACS instrument on-board HST. In this montage, I took all the data and so it also represents my science interests.

To quote James T. Kirk. Would you believe I built the digitizer myself to take this sample, on an Amiga 3000?

I hope you find this new web site easier to navigate. I actually had one of the first few hundred web sites back in ’93. And while my old one had what was once a particularly innovative image map, over time it became impossibly unwieldy to maintain. Hence this whole new arrangement, and I am ashamed to say, the use of authoring tools beyond “vi”.
