Hi! I’m currently finishing my PhD in Astronomy at the Universidad Nacional de Córdoba, specializing in computational relativistic astrophysics. My research focuses on relativistic compact objects, alongside the plasma dynamics and radiative processes in their surroundings. My PhD advisor is Prof. Dr. Oscar Reula, and I work in the General Relativity and Gravitation Group.

I’m the main developer of Skylight, a Julia-based tool for general-relativistic ray tracing and radiative transfer in arbitrary spacetimes. I’m very interested in Julia, a modern, dynamically-typed, high-performance programming language which aims to solve the two-language problem.

I also work in various projects related to compact objects, including modeling thermal X-ray emission from millisecond pulsars and exploring observational signatures of exotic compact objects. These projects involve applications of Skylight for producing images, light curves, and spectra. See my publications page for more details.
