Postdoctoral Researcher

• Worked on HGCAL sensor studies for the HL-LHC, including validation of non-irradiated sensors, studies of irradiated sensors, and leakage-current compensation using HGCROC input DACs.
• Main analyzer for the fully hadronic channel in non-resonant Higgs boson pair production in WWgg; responsible for data-driven background estimation, DNN-based signal extraction, and documentation for CMS-PAS-HIG-21-014.
• Contributed to differential cross-section measurements in H to 4l, introduced the n-jettiness observable, and expanded the interpretation with MadGraph_aMCatNLO and heavy-quark coupling constraints.
• Helped establish the first CMS evidence for semileptonic WW/WZ vector boson scattering with 4.4 sigma observed significance.
• Led CPPF data quality monitoring development for the CMS Level-1 trigger online DQM.

EGamma HLT Group Coordinator

• Served as CMS L3 EGamma HLT subgroup convener for Run-3 and HL-LHC preparations.
• Optimized electron and photon HLT energy regression, identification, isolation, and data-to-simulation scale factors.

Ph.D. Student / Researcher

• Sole analyst for the anomalous electroweak production search in semileptonic diboson final states, setting world-leading aQGC limits at the time.
• Contributed to the CMS GE1/1 GEM upgrade through detector assembly, characterization, beam tests, and laboratory setup at the University of Delhi.
• Corresponding author on the first GEM foils produced in India and led offline beam-test alignment studies that improved efficiency.
