I am a theoretical astrophysicist using magnetohydrodynamics simulations to model the Type I bursts: thermonuclear explosions on the surface of accreting neutron stars which resemble hurricanes of fire expanding till they engulf the whole star. The overarching goal of my research is to model the Type I bursts from beginning to end, studying them not just as isolated phenomena, but as events connected to their environment, accreting neutron stars in low-mass X-ray binaries, turning the bursts into probes of the neutron star physics.
I also enjoys developing numerical algorithms for different applications which led me to work on accretion, black holes, white dwarfs, astrophysical jets and the statistical interpretation of observational data.

Short CV

I graduated in Astronomy from the University of Padua, then moved to the Netherlands where I obtained my PhD degree from the Anton Pannekoek Institute for Astronomy. I held a Marie Curie Global Fellowship at Princeton University and the University of Southampton (UK) before joining the Institute of Astronomy of the National Autonomous University of Mexico as a tenure track. Now I am a Ramon y Cajal at UPC.
