I am a Research Associate in experimental high-energy nuclear physics, specializing in jet measurements and collective flow observables in relativistic heavy-ion collisions. My research spans detector construction and calibration (sPHENIX HCAL, ZDC, and sEPD), global reconstruction and analysis leadership, and the development of next-generation streaming workflows for the future ePIC detector at the EIC.
