Physics beyond the standard model in particle colliders and cosmology

The goal of my research is to understand the most fundamental constituents of energy and matter. This involves studying both the very smallest and the very largest length scales we are able to probe. Our current understanding of the basic constituents of nature is incomplete, and this has lead particle physicists to propose the existence of new elementary particles and forces. The most promising candidates include a new property of spacetime called supersymmetry, and new spatial dimensions of space that we can't see because they are are very small and curled up upon themselves. If either of these proposals is correct, we are likely to observe them in the next few years at the Large Hadron Collider (LHC) experiment. The primary focus of my research is to try to make sense of and to help discover these possibilities for new phenomena beyond what we have discovered so far.
