My research encompasses broad area of formation and evolution of galaxies, their halos and the inter-galactic medium. I use gravity+hydrodynamics simulations of structure formation in the universe to understand the cycling of baryons between galaxies and their surroundings. This includes topics of galactic infall, outflows, interactions, long term regulation of galaxy evolution and related observable consequences of these processes. I'm also interested in advances in numerical hydrodynamic techniques and physical models used in galaxy formation.
