Welcome! I am a Hubble Fellow at the Smithsonian Astrophysical Observatory, part of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, USA. My research program is focused on making empirical measurements that can help determine the physical conditions of the gas and dust in protoplanetary disks around young stars. I am particularly interested in mapping the mass distributions in these disks, and trying to relate that information to their evolution and the formation of planets in our Solar System and other extrasolar planetary systems. For most of this work, I use radio interferometers to image the emission signatures of dust grains and gas molecules in these disks at high angular resolution.
