I'm a physicist working in experimental high-energy and nuclear physics, with ongoing involvement in the STAR experiment at RHIC and the ePIC experiment at the EIC, both at Brookhaven National Laboratory. My research focuses on understanding nucleon structure, proton spin, and its 3D imaging to uncover the fundamental properties of matter.
