I chair the CfA OIR Time Allocation Committee that oversees our use of MMT, Magellan, and FLWO telescopes. I direct the Smithsonian's Telescope Data Center, a group that archives, processes, and distributes data from our telescopes on a nightly basis. I also build new instruments for our ground-based telescopes. I am PI of the SAO Widefield InfraRed Camera (SWIRC), a near-infrared imager for the MMT telescope that I took from proposal to commissioning in 13 months, and PI of the the MMT Cam optical imager.
