What I will be working on:

I plan to work on the search for the production of three massive vector bosons and measurement of triple and quartic gauge boson couplings. The full Run II data yields a unique opportunity to make the first experimental observation of the triboson production process at the LHC. I will focus on improving the well established 2016 analysis by machine learning technique to suppress the dominant backgrounds, including diboson backgrounds and fake lepton backgrounds from jets. I will also keep involving in Exotica searches, including serving as the EXO photon contact, and continue the long-lived particle search with delayed photons with full Run II data.

My role in CMS past and present:

I joined CMS in 2015 as a graduate student at Caltech. Since then, I have been worked on ECAL energy calibration with pi0 to diphoton events, Mip Timing Detector sensor tests and simulations in the characterization of timing precision of the sensor geometry, SUSY searches with Higgs to diphoton as final states using Razor variables, and long-lived particle search with delayed photons.
