FACULTY

Current Research

I am an experimental particle physicist and my research is driven by a curiosity about the underlying structure of the universe and the forces that govern the interactions of matter. I am an active member of the Compact Muon Solenoid (CMS) collaboration at the Large Hadron Collider (LHC) at CERN, one of the most sophisticated and high-energy experimental facilities in the world. Within the CMS collaboration, my research is centered on probing the Standard Model of particle physics and searching for evidence of physics Beyond the Standard Model. In parallel, I contribute to the Electron-Ion Collider (EIC) program as part of the EPIC detector collaboration at Brookhaven National Laboratory (BNL), which aims to explore the internal structure and dynamics of nucleons and the properties of visible matter, beginning with its most fundamental constituents: quarks and gluons.
In the past, I focused on studying the production of top quark pairs (tt-bar) in proton-lead collisions and measuring photon-induced processes in ultra-peripheral heavy-ion collisions using the ATLAS detector. In 2019, we discovered light-by-light scattering in heavy-ion collisions for the first time. Before joining the ATLAS collaboration, I worked with the ALICE experiment at the LHC, where I studied Multiple Parton Interactions (MPI) and the multiplicity dependence of charged particle and strange hadron production in proton-proton collisions. My doctoral research focused on searching for a heavy bottom baryon resonance state, Λ_b^{*0}, as predicted by the Standard Model, using data from the Collider Detector at Fermilab (CDF). In 2013, we found the first evidence of this resonance state at Fermilab.

Present Research Interests:

  1. Multiple Parton Interactions (MPI), their implications for QCD modeling and role in hadronic collisions
  2. Jet physics, including the jet substructure techniques
  3. Top quark physics and as a probe for new physics phenomena
  4. Phenomenology of the quark-gluon plasma (QGP) and deep inelastic scattering (DIS) processes
  5. Development and optimization of particle detector instrumentation for Phase-2 upgrades at the High-Luminosity LHC (HL-LHC)
  6. Detector and software development for the next-generation EPIC detector at the Electron-Ion Collider
Beyond addressing fundamental questions in high-energy physics, I am actively engaged in R&D efforts aimed at advancing particle detector development for better timing and spatial resolution, and radiation-tolerant detectors. My work aims to bridge experimental analysis, theoretical modeling or phenomenology, and detector instruction to help deepen our understanding of the universe at the most elementary level.
