I developed my Ph.D. at the Instituto Argentino de Radioastronomía (IAR), and I am currently a post-doctoral researcher at the Rochester Institute of Technology (RIT). My main expertise lies in General Relativistic Magnetohydrodynamics and High-Performance computing. I am also involved in Radio Astronomy, with a specific interest in pulsar observations and timing. I enjoy discussions on Foundations of Physics, as well. Beyond academic research, I have strong interests in applying my expertise to resolve the world most pressing problems.
