Research interest:
I am a theoretical astrophysicist. My research focuses on understanding the underlying physics of the high energy universe, including systems containing black holes of different scales and neutron stars of different species, relativistic jets launched from these systems as well as their interaction with the ambient medium. Most of my research papers are dedicated to understanding gamma-ray bursts (GRBs), the most luminous explosions in the universe, but my publications also cover a wide range of topics in astrophysics, including gamma-ray and radio pulsars, magnetars, active galactic nuclei, tidal disruption events, white dwarfs, neutrinos and cosmic ray physics, dark matter, strange quark stars, etc. Lately, I am actively working in two emerging, exciting fields in astrophysics: multi-messenger (gravitational wave sources and their electromagnetic counterparts) astrophysics, and the physics of mysterious fast radio bursts (FRBs).
