Munshi's work focuses on utilizing hydrodynamic simulations to study galaxy formation- in particular, the formation and evolution of the smallest and dimmest galaxies- in an effort to constrain the nature of dark matter. Because they are so small, dim and dominated in mass by dark matter, these galaxies are thought to be pristine laboratories for understanding dark matter through astrophysics.  Munshi's simulations are run on national supercomputing facilities, including NSF's Frontera, one of the world's fastest supercomputers.
