I plan to work on a search for HH→bbVV where one of the vector bosons decays leptonically, and the other decays hadronically. The main difficulties of this analysis are controlling the top background and estimating to multi-jet background and related systematic uncertainty. I plan to overcome the challenges by utilizing graph neural networks and my experience in H→𝜏𝜏 analyses. This analysis will also significantly broaden ongoing di-Higgs efforts at the LPC as we aim to cover a new final state, thus far not explored at CMS. In addition, I intend to work on developing and testing a readout chip of the MIP Timing Detector, which is on the critical path of the Phase II upgrade of the CMS detector for the high luminosity LHC.
Starting from 2017, I joined CMS. Since then, I have made leading contributions to the measurements of the Higgs boson properties, such as the simplified template cross-section, differential cross-section, and anomalous coupling with H→𝜏𝜏 decay as well as to the Phase I upgrade of hadronic calorimeter of the CMS detector.
