About me

I am currently visiting Prof Luis C. Ho at the Kavli Institute for Astronomy and Astrophysics (KIAA), Peking University, and a Research Affiliate in the Department of Physics and Astronomy at the University of Utah, USA. I am a very-high-energy (VHE) gamma-ray astrophysicist with extensive experience in stereoscopic observations using the Very Energetic Radiation Imaging Telescope Array System (VERITAS). My research focuses on time-domain variability, broadband spectral energy distribution (SED) modeling, and non-thermal emission from blazars, active galactic nuclei (AGN), and relativistic jets. I use Gammapy and multiwavelength observations from facilities including Fermi-LAT, Swift, XMM-Newton, and NuSTAR to investigate high-energy emission processes. I also conduct photoionization modeling using CLOUDY to probe the physical conditions and gaseous environments surrounding supermassive black holes, particularly in the broad-line regions of AGN.
