Research is focused on understanding 1) the details of the expansion process which can be deduced from the flow pattern of the detected particles. 2) The transport properties of the QGP by studying how the various self-generated probes such as jets and photons are modified by the fireball. Our research is carried out at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory and at the Large Hadron Collider (LHC) at CERN. Our group is involved with the STAR and ATLAS experiments respectively, at each of these accelerator facilities. Both experiments provide a diverse array of thesis research topics, an excellent working environment involving interactions between hundreds of scientists in the field, and unique opportunities for career development.
