Dwarf Galaxies - Observations		I have been a Clay Fellow at the Harvard-Smithsonian Center for Astrophysics since September 2006, before which I was a James Arthur Fellow at NYU's Center for Cosmology and Particle Physics. My overarching research goal is to advance our understanding of the Universe on small (~ 1 Mpc) scales in a cosmological context. Within the last decade, observations of the cosmic microwave background and distant supernovae have shown us that the Universe on scales where gravity dominates structure formation appears to be in good agreement with the predictions of currently favored Cold Dark Matter (CDM) cosmological models. However, baryonic physics dominates on scales ~ 1 Mpc, making it difficult to understand the small-scale structures of the Universe in a cosmological context. Moreover, both ground- and space-based observations of galaxies over a range of masses and cosmic ages have raised possible challenges to the CDM paradigm. My primary approach to this field has been to improve our understanding of galaxy formation and evolution using a combination of observational and computational resources. My research foci thus far have been a search for new Milky Way companions using Sloan Digital Sky Survey data and an investigation of disk and dwarf galaxy formation using SPH+N-body cosmological simulations.
