I am an astrophysicist specializing in the study of accretion and ejection processes in compact objects, including black holes, neutron stars, and white dwarves. I study the varied electromagnetic emissions from these different astrophysical systems - starting from the supermassive black holes entrenched at the cores of distant Active Galactic Nuclei to the stellar-mass black holes and neutron stars within our own galaxy - aiming to understand the complex physics of astrophysical jets and discs. My investigations extend to the coupling between accretion and ejections in these systems, unraveling the processes within accretion discs and elucidating the relativistic nature of jets. The scale invariance of black hole physics across the entire mass spectrum is a central theme in my work. Leveraging state-of-the-art observations across the electromagnetic spectrum (from radio and infrared to optical, ultraviolet, and X-ray wavelengths) and employing theoretical modeling, I explore the environments characterized by extreme gravitational fields.
