Research CV Publication Students Collaborators Useful links Other Activities I mainly work on various research problems related to Active Galactic Nuclei (AGNs) (e.g. multi-wavelength variability of various classes of AGNs on divere time scales, Ultra  High Energy Cosmic Ray (UHECR) Emission from AGNs). These studies are ueful to understand the emission mechanism of various classes of AGNs. I also spend some time working on Gamma-ray Bursts (GRBs), black hole mass and spin in the transient Universe. My ongoing projects can be seen in research section of the webpage.
