I am a NASA Hubble Fellow and a Carnegie-Princeton Fellow at Princeton University.

My research focuses on the formation and evolution of dwarf galaxies and Ultra Diffuse Galaxies (UDGs), both in galaxy groups and in the field (isolated galaxies).
I use various observational tools such as the Dragonfly Telephoto Array, the Hubble Space Telescope, and the Keck telescope.

I like thinking about creative data-driven methods for exploring and discovering astrophysical objects and phenomena that were not known to us before.
