The physics of the standard model of the universe

In the broadest sense my research focuses on understanding the fundamental physical nature, history, and future of the Universe. It has long been known that, in the hot big bang model, the Universe once was in an extremely hot and dense state where high energy particle physics determined its evolution. There is an important and intimate connection between the physics of the very small (high-energy particle theory and perhaps string theory) and the physics of the very large (cosmology) and development and pursuit of this connection is the central focus of my research. By combining clues from laboratory experiments, cosmology and astrophysics we have already learned much about the fundamental physics that governs our Universe and I believe, right now, we are on the brink of discovering much more.
