Research & Expertise

🌌

Research Focus

Specializing in extragalactic astronomy and high-energy astrophysics, with a focus on AGN, relativistic jets, and blazars. These cosmic powerhouses emit intense X-rays and gamma-rays, revealing the most energetic processes in the universe.

💻

Computational Methods

Employing Cloudy photoionization simulations to model the complex interplay of radiation and matter in AGN environments. Multi-wavelength data reduction from NuSTAR, Chandra, XMM-Newton, Swift, NICER, and Fermi.
