I am an observational astronomer focusing on imaging of dusty disks around nearby stars. My research programs primarily utilize the Hubble Space Telescope, Keck Observatory and the Very Large Telescope, with additional programs conducted with Gemini Observatory, the Spitzer Space Telescope, Lick Observatory, the James Clerk Maxwell Telescope, and the Very Large Baseline Array. Some of my accomplishments are the optical discoveries of debris belts surrounding the nearby stars Fomalhaut and AU Microscopii.

I am currently an Associate Adjunct Professor in the Astronomy Department at the University of California, Berkeley.
