Research Areas

My research interest can be broadly categorized into the following.

  1. Neutrino Physics: Origin of mass, mixing; new interactions; sterile neutrino; Dirac nature of light neutrinos; neutrino cosmology.

  2. Dark matter: production mechanisms in the early universe; dark matter interactions and detection aspects; possible common origin of dark matter and neutrino mass.

  3. Origin of matter-antimatter asymmetry: Baryogenesis via leptogenesis, electroweak baryogenesis, dark matter induced baryogenesis.

  4. Cosmic inflation and early universe phase transitions within minimal extension of standard model of particle physics, probing such scenarios with stochastic gravitational waves.
