The surprising discovery of neutrino mass and mixing leads to the obvious question: what other unexpected properties might neutrinos have? IceCube data provides a unique window on the highest energy neutrinos ever observed. It is an ideal place to search for new Beyond Standard Model effects and is the main focus of my group.

IceCubeLabThe IceCube detector is buried in the Antarctic continent glacier, close to the geographic South Pole. IceCube observes neutrinos that are up to six orders of magnitude higher in energy than those produced at accelerators today. Most of these neutrinos are produced in the collision of cosmic-rays with the Earth atmosphere, while the rarest of them are neutrinos of cosmic-origin that come from some of the most extreme environments in the Universe. The group develops new techniques to study these neutrinos and characterize them in order to search for new neutrino physics and understand the origin of the high-energy astrophysical neutrino flux.

The IceCube experiment is currently undergoing an upgrade: the addition of an array of more tightly packed detectors in the inner part of the current array. The group participates in the development of this new detector and enhancement of its physics reach capabilities.

mioThe second phase of the IceCube upgrade is called IceCube-Gen2 and is expected to be deployed in the upcoming decade. IceCube-Gen2 will consist of an approximately ten times larger array that will allow to see smaller neutrino fluxes and study feeble neutrino interactions. This group supports our experimental work with neutrino phenomenology and global fits to the neutrino data. Students in this group will be involved in the full arc of an experimental analysis: from idea to result.
