My research interests are focused on the search for new physics with the ATLAS detector at the Large Hadron Collider (LHC). The LHC permits the study of nature at a previously-unexplored energy scale. The first glimpse of beyond the SM physics could be just around the corner. In particular, I am interested in finding a resolution to the "hierarchy problem" and understanding the nature of dark matter.
The mass of the Higgs boson has been measured experimentally and found to be many orders of magnitude smaller than the theoretical prediction. This contradiction between experimental observation and theoretical expectation is referred to as the “hierarchy problem.” I am currently conducting a search for exotic decays of the Higgs boson to new, long-lived particles. If observed, these new particles could help to resolve the hierarchy problem.
Approximately 27% of the universe is composed of a mysterious substance known as "dark matter." I also contribute to searches for the production of dark matter in collisions at the LHC.
I am also involved in preparations for an upgrade of the innermost ATLAS sub-detector, the pixel detector. The pixel detector allows reconstruction of collision vertices and the identification of bottom quarks, the most common Higgs boson decay product.
