I am a professor in physics by training. I am currently working on three research projects. The first project is to study the matter properties at extreme temperature and density by colliding relativistic heavy ions at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Lab. The second project is to study the properties of cosmic ray radiation and the associated applications. The third is to develop detector technologies for hadron identification in Electron-Ion Collider experiments.
