My research focuses on the dynamics of compact objects (black holes and neutron stars), and their interactions with the surrounding plasma or with a stellar companion within a binary system. I explore the complex physical processes governing these systems, such as accretion, relativistic jets, and radiative feedback, which are critical for understanding their evolution and observational signatures. A significant aspect of my work also involves studying massive stars, especially those in X-ray binaries, where compact companions influence stellar winds and mass transfer dynamics.

I employ advanced numerical simulations, using techniques like magneto-hydrodynamics (MHD) to model plasma behavior and particle-in-cell (PIC) methods to capture kinetic processes in relativistic environments. These simulations often rely on high-performance computing, enabling me to achieve multi-scale and multi-physics insights into phenomena such as jet formation, magnetic reconnection, and accretion disk instabilities. My expertise lies in bridging observational data from facilities like ALMA and the VLT with theoretical predictions, providing a holistic understanding of compact objects and their environments. Through this work, I contribute to fields ranging from gravitational wave astrophysics to the study of gamma-ray bursts and active galactic nuclei.
