The pioneering work on Quark Gluon Plasma is already well recognised internationally. He lead the team from India to participate in the experiments at CERN, Geneva, as well as RHIC and BNL, USA, a first of its kind from India. He along with his colleagues established the thermometric signals of Quark Gluon Plasma as a definitive signals; already confirmed by experiments. Recently, his breakthrough work on Hawking radiation and entropy from the relic of QCD phase transition, at the primordial epoch of a few microseconds after the big bang and its signatures in the universe has made a tremendous impact.
