Research Focus

Relativistic hadronic collisions experiments and phenomenology.

As an active researcher within the ALICE Collaboration, my primary focus lies in unraveling the collective dynamics of the Quantum Chromodynamics (QCD) medium, currently driving my experimental analysis using the newly collected LHC Run 3 data. My work bridges experimental data analysis and phenomenological modeling, specifically targeting the emergence of medium-like behaviors in small and light-ion collision systems at the LHC energies.

By leveraging both experimental measurements and Monte Carlo event generators, I aim to disentangle the effects of true thermalized media from other QCD mechanisms. Beyond offline physics analysis, I actively participated in ALICE data taking during Run 3, serving as a Shift Leader for 30 days and an Experiment Control System (ECS) operator for 12 days. I also contributed directly to detector performance by involving in particle identification (PID) quality assurance for the TPC and TOF detectors.
