My research focuses on using astrophysical observations to understand the fundamental nature of dark matter and dark energy. I work on large cosmic surveys including the <a href='https://www.darkenergysurvey.org'>Dark Energy Survey (DES)</a> and the <a href='https://www.lsst.org'>Large Synoptic Survey Telescope (LSST)</a>. Recently, I have been interested in using the faintest and most dark-matter-dominated galaxies to try to understand the fundamental nature of dark matter. I consider myself to be an experimental particle cosmologist, and I am heavily invested in the instruments and infrastructure that make these large surveys possible.

Ongoing Scientific Projects:

• Dark Energy Survey (DES)
• Large Synoptic Survey Telescope (LSST)

Past Scientific Projects: Fermi Gamma-ray Space Telescope (Fermi)
