I am a Chancellor's Postdoctoral Fellow at the University of California, Santa Cruz. ​I am part of the UCSC Astrobiology Initiative. I am currently a member of the Telescope Array Collaboration and a visiting scientist at RIKEN (ABBL) in Japan. I am also part of the Simons Collaboration on Extreme Electrodynamics of Compact Sources (SCEECS).

I conduct interdisciplinary research on the role of cosmic radiation in the emergence of life, involving knowledge from different fields. While biologists have not yet reached a consensus on the definition of life,   homochirality - the specific molecular handedness of biomolecules -  is a phenomenon only produced by life. The goal of my research is to understand if spin-polarized cosmic radiation can act as a chiral evolutionary pressure. I am performing experiments to understand chiral selective light-biopolymers interactions and experiments with spin-polarized muons to test this idea.

My other topics of interest are theoretical High Energy Astrophysics and Multimessenger Astrophysics. I study the formation of relativistic jets around spinning black holes, and build theoretical models to interpret the observations of M87 radio galaxy - from the region close to the black hole where the recent EHT observations are key to understand the physics at play in jet formation, to hundreds of light-years away from the galaxy's core, where the jet profile provides insight into the collimation mechanisms.

 

I also investigate the origin of ultra-high energy cosmic rays, UHECRs, the most energetic particles in the Universe. I developed codes to calculate the acceleration of cosmic ray nuclei at mildly relativistic shocks associated with relativistic jets, their propagation in Galactic and extragalactic magnetic fields to predict cosmic-ray anisotropies, and the fluxes of secondary neutrinos and gamma-rays expected from various types of cosmic-ray sources to make predictions for future neutrino facilities.
