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. Alongside my experimental work, I use PYTHIA 8 to understand mechanisms such as multi-parton interactions (MPI) and Color Reconnection (CR) that can reproduce features resembling QGP-like behavior without invoking a thermalized medium. My research further extends into baryon number transport and heavy-flavor hadronization.
