​​I am an astrophysicist at the Instituto de Astronomía, Universidad Nacional Autónoma de México. My research focuses on the stage of the violent, high-energy universe and its invisible actors: magnetic fields, cosmic rays, and neutrinos. These non-thermal components govern some of the most extreme phenomena in astrophysics, yet they remain among the least understood. We still do not understand the structure of black holes and neutron stars magnetospheres, and how relativistic jets form. The Event Horizon Telescope imaged the relativistic plasma orbiting a six-billion-solar-mass black hole revealing the base of the jet itself in the now iconic image. While these observations suggest that black hole spin powers relativistic jets via the Blandford–Znajek mechanism, they do not clarify the plasma's nature or the energy transport pathways, even though jets from active galactic nuclei (AGNs), critically influence galaxy evolution, star formation, and produce some of the brightest emission observed across the electromagnetic spectrum, and are potentially associated with high energy cosmic rays and neutrinos. In gamma-ray bursts (GRBs), relativistic jets appear in a completely different astrophysical setting. GRBs are short-lived but extremely energetic events, where jets are launched during catastrophic phenomena such as the collapse of massive stars or the merger of compact objects. The association of both long and short GRBs with relativistic jets has been firmly established, most notably by the multi-messenger detection of GW170817. These events provide a unique laboratory to study jet physics under extreme, rapidly evolving conditions, complementing the study of jets in AGNs and tidal disruption events (TDEs).

I also conduct interdisciplinary research on the role of cosmic radiation in the emergence of life. The goal is to understand if polarized cosmic radiation can act as a chiral evolutionary pressure and drive the necessary out-of-equilibrium chemistry. We design experiments to test this idea at muon sources. I also investigate how nearby supernovae can imprint both transient cosmic-ray signatures and long-term effects on Earth.
