About

I am a researcher in particle astrophysics and high-energy particle physics. Among my research interests are high-energy atmospheric and astrophysical neutrinos, ultra-high energy cosmic rays and hadronic interactions. I contribute to the IceCube Neutrino Observatory located at the geographical South Pole in Antarctica. My main expertise is on high-precision atmospheric neutrino flux computations and hadronic interactions.
