Born in northern Spain, I completed my undergraduate studies in Physics with a specialization in Theoretical Physics at the Complutense University of Madrid in 2020. As part of my academic career, I had the opportunity to spend a year abroad at the KTH Royal Institute of Technology in Stockholm.Following my undergraduate studies, I received a scholarship from the Laboratoire d'Excellence UnivHearthS (CNRS) to pursue the M2 NPAC master's program at Sorbonne Université, Paris-Saclay Université and Université de Paris. During this time, I had the privilege to work at the Observatoire de Paris under the direction of Alain Albouy and Jacques Féjoz. I was financially supported by the Université Paris Dauphine - PSL.Currently, I am pursuing a PhD in Numerical Relativity, where I have been appointed FPI researcher under the supervision of Carlos Palenzuela and Joan Massó. My research focuses on numerical simulations in general relativity, studying the merger of compact objects (black holes and neutron stars), and modeling the gravitational and electromagnetic wave signals driven by these systems. In particular, I am interested in modeling the interactions of neutrinos with matter in the post-merger remnants. This is an incredibly challenging computational problem that I am tackling by combining Monte-Carlo simulations with approximate methods such as the moments formalism. Most of my work is done using two different codes: MHDuet [http://mhduet.liu.edu/] (open source GRRMHD code with adaptive mesh refinement), and my own parallelized GPU Julia code called MINGUS (which combines high-resolution shock capture methods and Monte-Carlo algorithms), which will soon be publicly available.
