This group studies the role of neutrinos in stellar evolution, the dynamics of core-collapse supernovae, neutron stars, and the early  Universe, the solar neutrino problem, dark matter detection, neutrino effects in type-II supernovae. It also studies the related area of r-process nucleosynthesis, and constraints on neutrino properties from astrophysical  observations. 

The theoretical nuclear group maintains close contacts with other institutions in this country (e.g. Michigan State, National Institute for Nuclear Theory (Seattle), Argonne National Laboratory and Lawrence Berkeley Laboratory) as well as in Australia, Japan, Europe and Latin America, which result in collaboration and frequent visitors from those institutions. Research is currently being pursued here on compound and pre-equilibrium effects and statistical fluctuations in nuclear reactions, high energy heavy-ion reactions with projectile fragmentation, nuclear multi fragmentation, deeply inelastic heavy-ion collision, phase transitions in nuclear and hadronic systems, nuclear structure and symmetry principles, supersymmetry in many-body systems, semi-classical techniques applied to heavy ion reactions, and collective effects in nuclear reactions and models.
