Fields of Study: High Energy Physics 

 

Research Interests: 

 

I work with the Arizona Experimental High Energy Physics group on the ATLAS Experiment, one of the primary physics detectors at the Large Hadron Collider (LHC) at CERN. My primary research interest is in understanding the nature of the Higgs Boson, the most recently-discovered fundamental particle. I am especially interested in searching for “di-Higgs” production (creating two Higgs Bosons in high energy proton collisions at the LHC). Di-Higgs production probes how the Higgs Boson interacts with itself, which could illuminate big questions, such as: why there is so much more matter than anti-matter in our universe; what will happen to our universe in the distant future; and whether our current understanding of how the Higgs boson comes to exist is correct. My research includes upgrades of the ATLAS detector and applications of machine learning to physics data analysis in order to improve future Higgs boson measurements both now and in the upcoming High-Luminosity LHC era.
