Research Interests
One of the central pillars of modern high-energy physics is the exploration of phenomena beyond the Standard Model (BSM) at the Large Hadron Collider (LHC). My research focuses on both direct and indirect searches for new physics using the CMS experiment, with a particular emphasis on top quark physics, Standard Model Effective Field Theory (SMEFT) interpretations, and heavy resonance searches. As a Level-3 manager within the CMS Collaboration, I serve as the Convener for the B2G Resonance Subgroup and previously led the TOP EFT Subgroup, coordinating international efforts to discover heavy new particles and probe anomalous couplings.
Bridging experimental data with theoretical frameworks, I am heavily engaged in collider phenomenology and the reinterpretation of LHC results to expand the physics reach of existing datasets.
In addition to my physics analysis activities, I contribute to the CMS Phase-2 Upgrade program through detector instrumentation and performance studies aimed at preparing the experiment for operation at the High-Luminosity LHC. My efforts are centered on the Barrel Timing Layer (BTL) of the MIP Timing Detector (MTD), which provides precision timing measurements essential for mitigating pileup effects in the HL-LHC environment. I have been deeply involved in the testing, commissioning, and performance validation of BTL detector modules, while also contributing to the design, development, and deployment of the detector control system that ensures reliable detector operation.
