I earned my Bachelor’s Degree in Physics at the University of Santiago de Compostela (USC) in 1994 and completed my PhD in Astroparticle Physics at USC in 1999. Afterward, I held postdoctoral positions at the Univ. of Wisconsin-Madison and the Bartol Research Institute at the Univ. of Delaware, USA. In 2003, I returned to USC with a postdoctoral contract, followed by a five-year Ramón y Cajal contract in 2004. I became an Associate Professor (Profesor Titular) in 2010 and a Full Professor (Catedrático) in 2023.
My research centers on Astroparticle Physics, focusing on Ultra-High Energy Cosmic Rays (UHECRs) and neutrinos, particles arriving from unknown cosmic sources with energies above 1 EeV - over a million times higher than protons accelerated at CERN\'s LHC. The goal is to identify the sources, nature, and acceleration mechanisms of these particles to understand extreme astrophysical phenomena and fundamental physics. I am a senior member of the Pierre Auger Collaboration, a gigantic UHECR detector array in Argentina, involving over 450 researchers from 17 countries. Since 2008, I have co-led the Neutrino and Neutral Analysis Tasks in Auger.
As a pioneer in using MHz-GHz radio waves to detect UHECRs and neutrinos, I’ve developed the ZHS and ZHAireS simulation codes and contributed to several experiments on radio detection using Antarctic ice, the Earth\'s crust and atmosphere and even the Moon as target. I have a strong interest in multi-messenger astronomy, in particular on linking sources of gravitational waves with neutrino and cosmic ray detections.
Throughout my career, I have published around 195 papers, supervised six PhD theses with 3 more in progress, and delivered over 50 presentations at major conferences. I have been the principal investigator on several national and regional projects and have held key roles within USC’s Department of Particle Physics and the Instituto Galego de Física de Altas Enerxías (IGFAE).
