Research Statement

My research is focused on the formation of structure in the Universe. I did my PhD work on the formation of galaxies, galaxy clusters and superclusters. More recently I started studying the formation of smaller things: planets. Along the way, my collaborators and I have considered a variety of other topics including accretion flows onto supermassive black holes, galaxy dynamics, hypervelocity stars and behavior of dark matter. Much of my work depends on parallel supercomputers to extract the science, and I am grateful to NASA for the generous allocation of compute cycles.
