My research focuses on dwarf galaxies and the connection between the galaxies and their host dark matter halos. I combine theoretical models, numerical simulations, and astronomical survey data to study dwarf galaxies and the galaxy–halo connection, answering questions about the nature of dark matter, galaxy formation physics, and the uniqueness of our own Milky Way.
