PhD Candidate in Physics (Kent State University, expected 2026)
Theoretical (Phenomenological) High-Energy Physics or Nuclear Physics • Heavy Ion Physics • Heavy Flavor Production and Modification in Heavy Ion Collisions and Small Collisions in LHC AND RHIC • Quarkonium Transport in QGP • Open Quantum Systems • Quantum Computing

I’m a physics PhD candidate studying the transport, suppression, and regeneration of quarkonia (especially bottomonium/charmonium) in the quark–gluon plasma (QGP) formed in high-energy nuclear collisions like in Large Hadron Colliders (LHC) in CERN or Relativistic Heavy Ion Collider (RHIC) at New York, USA. My work uses both semi-classical transport / kinetic approaches and quantum approach like open quantum systems (OQS) methods (Lindblad evolution as a quantum-transport description), as part of the HEFTY Collaboration.

In parallel, I’m interested in quantum computing for high-energy physics, especially quantum algorithms for lattice gauge theories and longer-term directions like real-time dynamics and scattering, where classical approaches (lattice QCD) face major limitations.

I’m also learning AI/ML and exploring how it can support scientific workflows (HEP now; broader domains like medicine/healthcare).

• Quarkonium transport in QGP: suppression and phenomenology in (p)–Pb and (AA) collisions (RHIC/LHC).
• Quantum Transport: Using Open Quantum Systems (coupled to pNRQCD), Lindblad-based real-time evolution for heavy quarkonium in hot nuclear matter.
• Semi-classical modeling: kinetic-rate / transport frameworks (semiclassical with rates computed from perturbative or non-perturbative ways).
• Quantum computing for HEP: lattice gauge theory workflows (state preparation, adiabatic, variational methods, benchmarking), scattering experiments (real-time dynamics).
• Scientific computing & reproducibility: simulation pipelines, analysis, plotting, and version-controlled research code.
