About
My research focuses on compact objects which are mostly related about the black holes. I have tried to understand the properties of the accretion disk around the black holes, instabilities of the accretion disks, astrophysical jets and jet dynamics, and properties of the astrophysical plasma. My research involves theoretical and numerical studies and I have a great deal of experiences in determination of properties of the accretion disk and their dynamical instabilities around the stellar and massive black holes. I am also currently conducting research on the expansion of the universe, wormholes, and the existence of dark matter.
