About

I am a Postdoctoral Fellow at the Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune, and a former Ph.D. scholar in Extragalactic Astronomy at the Department of Physics and Astronomical Science, Central University of Himachal Pradesh. My research focuses on the multi-wavelength investigation of the nature and environment of active galactic nucleus (AGN), with emphasis on spectral energy distribution (SED) modelling, variability analysis, and spectroscopic studies.
