Research Activity

PhD Work

My doctoral thesis involves a likelihood search for NSIs with 10 years of atmospheric muon-neutrino data recorded with ANTARES. It also deals with the estimation of the discovery potential of KM3NeT-ORCA (ORCA in what follows) for NSIs based on detailed detector simulations. Moreover, the thesis also addresses the phenomenological implications of NSIs on the neutrino mass ordering (NMO) sensitivity at ORCA. In addition, the sensitivity of ORCA towards disentangling the octant of θ23 has also been investigated within the scope of the PhD.

Masters project

The Master thesis project entailed a sensitivity study of the INO@ICal experiment towards measuring the atmospheric neutrino oscillation parameters.
