Research Interests

Radio-loud AGNs (blazars and radio galaxies), from an X-ray, gamma-ray, and multiwavelength perspective;
physics and environment of extragalactic jets; unification models for AGN;
origin of the high-energy emission from jets;
low-luminosity accretion in AGNs and LINERs;
high-resolution X-ray spectroscopy of AGNs.

Current Projects

I am currently working on High-energy observations and interpretation of Active Galactic Nuclei (jets and radio-loud sources).
