I study high-energy particles from space – cosmic rays and neutrinos. Cosmic rays are naturally accelerated, charged nuclei from yet unidentified astronomical objects. When interacting with matter or radiation, cosmic rays cascade into secondary particles like photons and neutrinos. These messengers are not deflected by magnetic fields, opening a new gate for astronomical observations. I freely move between theory and experiment, particle physics and astrophysics. I am part of the IceCube Neutrino Observatory, a detector built inside a cubic kilometer of natural glacier ice at the South Pole in Antarctica. I aim to further improve the computational methods to solidify the weakest signals and find true anomalies in data that are not caused by detector or modeling systematics.
