My research interest includes studying the properties of neutrinos (including various features of neutrino socillation) in context of wide range of astrophysical sources like core-collapse Supernovae, binary neutron star mergers etc to unreveal the astrophysical properties associated with such sources. To be more specific, I am currently involved in understanding the physics behind fast collective neutrino oscillation which can occur in the very dense interior of such astrophysical sources where neutrino density is very high and can have interesting consequences in the evolution of such sources.
