Welcome to my website. I am a theoretical astrophysicist. I'm interested in theoretical and numerical astrophysics around black holes, exotic objects, and other high-energy astrophysical phenomena, such as relativistic astrophysical plasma in the universe. My research targets understanding accretion phenomena and, with that, finding observational signatures that we can detect. Currently, I am working with the general relativistic magnetohydrodynamics code BHAC (Black Hole Accretion Code) to accommodate microphysics such as two-temperature flow and variable adiabetic index. Also, developing the code to study accretion flow in any general spacetime can be useful in testing the Einstein theory of gravity or any alternative theories.
I am also a member of Event Horizon Telescope (EHT) collaboration. Currently, I am working in the M87 theory group and in the gravitational physics working group.
