General

The main goal of our research is to recreate the primordial state of visible matter in the Early Universe by colliding heavy-ions at ultra-relativistic speed. We try to understand the production and dynamics of a strongly interacting matter called quark gluon plasma (QGP) created in heavy-ion collisions.
