Dr. Arvind Kumar's research interest includes study of mass modification of hadrons at finite density and temperature of the hadronic medium. The applications of these studies are for heavy- ion collision experiments as well as for understanding the properties of astrophysical objects e.g. neutron stars. My research interest also includes the study of dynamics of Quark Gluon Plasma (QGP) and quarkonium suppression at LHC energies.

Dr. Rajesh Kumar works in the field of the Astroparticle physics which deals with the study of Equation of State of compact stars. In his doctorate, he studied the in-medium properties of hadrons under the extreme conditions of temperature and density in a model dependent framework.
