Research Interests

My research is focused on understanding the fundamental particles and forces with colliders. I use the data collected by the Compact Muon Solenoid (CMS) detector at the Large Hadron Collider (LHC) to search for the unknown particles such as those predicted in the supersymmetry theories, and stringently test the current theory: the Standard Model by measuring very rare and challenging processes with multiple bosons. My current focus is on novel ways to measure the Higgs potential. 

I am also passionate about advancing our capabilities in studying nature's secrets. My current endeavor is to apply machine learning techniques in our trigger and data acquisition system, in order to unleash the physics potential of the LHC/High-Lumi LHC (HL-LHC) data. I led the testing and commissioning of the forward pixel detector Phase 1 upgrade, that is a 'camera' sitting at the 'heart' of the CMS detector providing the most precise 3D measurements of charged particle tracks. I am excited to apply my expertise to the next upgrade of the CMS tracker in preparation for HL-LHC data-taking.
