I am a Professor in the Astronomy Department and Physics Department at Yale University.

My research focuses on the origin and evolution of dwarf galaxies with the goal of using these objects to answer fundamental questions in astrophysics and cosmology. My research group uses the world’s largest telescopes to study the smallest galaxies in the Universe.
