My research focuses on understanding the nature of Dark Matter and our galaxy, the Milky Way. In particular, I use dwarf galaxies and stellar streams as cosmological probes of dark matter and as probes of the accretion history and mass distribution of the Milky Way. To, accomplish these goals I am deeply involved in a several wide-field ground based optical/near-infrared photometric surveys. Currently, I am a member of the Rubin Observatory Commissioning team and one of the conveners of the Dark Matter Working group inside the Dark Energy Science collaboration (DESC). I also am a builder for the DECam Local Volume Exploration Survey (DELVE), and am a member of the Milky Way working group within the Dark Energy Survey (DES).
