Summary Particle physicist at Purdue University working on Higgs physics, vector boson scattering, and precision electroweak measurements at the LHC. Research spans collider-physics analysis, detector development (GEM, HGCAL), and scientific software within the CMS Collaboration.

Work

  • 2025.01 - Present
    Postdoctoral Research Associate
    Purdue University
    Higgs boson physics, high-mass Higgs searches, and resonant di-Higgs production within CMS.
    • Lead analyst for Higgs boson decay to muon pairs (H→μμ).
    • Main analyzer and contact person for high-mass Higgs search in ZZ→2l2q and 2l2ν (HIG-23-001).
    • Leading resonant Higgs pair search in WWγγ final state (B2G-24-010).
    • Assessing and improving high-pT muon performance.
  • 2020.10 - 2022.08
    Co-convener, EGamma HLT Group
    CMS Collaboration
    • Optimized electron and photon HLT energy regression, identification, isolation, and data-to-simulation scale factors for Run-3.
  • 2019.12 - 2024.12
    Postdoctoral Researcher
    IHEP Beijing and CERN
    Higgs physics analyses, EGamma HLT coordination, and detector R&D within CMS.
    • Main analyzer for non-resonant HH→WWγγ (fully hadronic channel); CMS-PAS-HIG-21-014.
    • Contributed to H→4l differential cross-section measurements; introduced n-jettiness observable.
    • Helped establish first CMS evidence for semileptonic WW/WZ vector boson scattering (4.4σ).
    • HGCAL sensor studies for HL-LHC upgrade.
    • Led CPPF data quality monitoring for CMS Level-1 trigger online DQM.
  • 2012.10 - 2019.11
    Ph.D. Student / Researcher
    University of Delhi and CERN
    • Sole analyst for anomalous EW production search in semileptonic diboson final states, setting world-leading aQGC limits.
    • Contributed to CMS GE1/1 GEM upgrade: assembly, characterisation, beam tests, and alignment studies.
    • Corresponding author on first GEM foils produced in India.
