Professor Mohapatra is a theoretical particle physicist within the Maryland Center for Fundamental Physics (MCFP). His research interests include theory and phenomenology of neutrino masses, understanding the origin of parity in physics from beyond the standard model, the so-called left-right symmetric theories of weak interactions, grand unification of forces and matter, nature and origin of dark matter, understanding flavor patterns of quarks and leptons using higher symmetries as well as origin of matter (“Baryogenesis”). Theoretical paradigms and tools used in his research are those of quantum field theories with spontaneously broken gauge symmetries and supersymmetry. He has also worked on areas that question the fundamental assumptions of quantum field theory such as theory and phenomenology connected with possible violations of Pauli exclusion principle, breakdown of electric charge conservation and constraints on milli-charged particles. His ideas can be tested in non-accelerator experiments such as neutrino oscillations, searches for dark matter as well as searches for electric dipole moment and lepton flavor violation searches as well as searches in colliders such as the Large Hadron Collider. He also works on astrophysical constraints on particle physics such as those from supernova explosion, neutron stars etc. He also likes to give popular talks that explain the intricate details of particle physics activities.
