Navin's research spans various aspects of high-energy astrophysics and transient, multimessenger signals from compact object-binary stellar interactions viz., accretion around compact objects, emission mechanisms of high-energy non-thermal X-rays from black hole coronae, the physics of particle heating and acceleration in astrophysical plasmas (and the emission of high-energy neutrinos from them), and the origin of coherent radio emission from sources like Pulsars and Fast Radio Bursts. Navin studies them by performing kinetic plasma simulations (PIC), hydrodynamical fluid simulations, analytical pen-and-paper modeling, and also by directly observing the astronomical sources via satellite and ground-based telescopes.
