Astrophysical neutrinos provide a unique window into physics at extreme energies and distances, making them powerful probes of both fundamental interactions and the environments in which they are produced. In this presentation, I will discuss my ongoing research program focused on using neutrinos from astrophysical sources to investigate physics beyond the Standard Model and explore the astroparticle frontier.
I will first present phenomenological studies of beyond Standard Model scenarios using high-energy astrophysical neutrinos, with particular emphasis on probing leptoquark signatures at IceCube-Gen2 through analytical calculations and numerical simulations. I will also discuss current work on the cosmic neutrino background and its interactions with ultra-high-energy cosmic rays, including theoretical calculations and the reproduction of key results in the literature.
In addition, I will briefly describe exploratory work at the intersection of Artificial Intelligence and High-Energy Physics, focusing on interpretability and the extent to which machine learning models capture underlying physical structures and how those techniques can be adopted to astroparticle physics. Finally, I will outline the broader direction of my doctoral research and future plans toward developing a unified astroparticle phenomenology program based on astrophysical neutrino probes of new physics.
