I am an astrophysicist with research interests spanning high-energy astrophysics, astroparticle physics, and observational cosmology. My work focuses on the formation and evolution of supermassive black holes and active galactic nuclei, the co-evolution of galaxies and their central black holes, and the origin and evolution of the diffuse extragalactic radiation fields from the infrared to the gamma-ray regime. I am particularly interested in the extragalactic background light, the cosmic gamma-ray horizon, and the use of high-energy observations to probe the history of star formation, black hole growth, and the large-scale evolution of the Universe.
I actively collaborate on observations with a variety of ground- and space-based facilities across the electromagnetic spectrum. Among these, my long-standing favorites are the NASA missions Fermi, Swift, and NuSTAR, whose complementary capabilities have been central to many of my research projects.
