Dr. Yun Luo is an accelerator physicist in the Electron-Ion Collider Directorate at Brookhaven National Laboratory (BNL).  Before he joined BNL in 2003, he had been working on the Beijing Electron-positron Collider (BEPC) at IHEP  and the Large Hadron Collider (LHC) at CERN.  In 2006,  Dr. Luo proposed and demonstrated a global betatron decoupling feedback based on a continuous coupling measurement.  Dr. Luo carried out a sophisticated weak-strong beam-beam simulation for RHIC head-on beam-beam compensation with electron lenses, which became operational  in 2015 RHIC proton run and improved  the luminosity.  Dr. Luo was the run coordinator of the 2012 RHIC U-U and Cu-Au runs, during which he proposed new lattice configurations to greatly improve the off-momentum dynamic aperture and the beam lifetime.  Burning-off dominated physics stores and  peak luminosity exceeding initial one at the beginning of store were first observed in the U-U collision. Since 2016, Dr. Luo began to work on EIC accelerator physics design. Currently he is mainly working on EIC   beam-beam interaction simualtion studies, HSR dynamic aperture calculation / improvement with beam-beam and nonlinear magnetic field errors and other lattice or machine errors,  detector solenoid effect compensation in IR6,  HSR local and global betatron coupling correction. Dr. Luo also serves as the coordinator for RHIC Accelerator Physics Experiment (APEX) program since 2014.
