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. I am co-PI of the SAGA Survey.

I am on the Board of the Warrior Scholar Project (WSP) and helped develop the WSP STEM curriculum. I am the faculty director of the REVU Program.
