Jason Koskinen

D. Jason Koskinen is an Associate Professor at the Niels Bohr Institute, University of Copenhagen, specializing in Experimental Particle Physics. His primary research focuses on measurements of neutrino oscillation using the IceCube neutrino observatory, specifically the DeepCore sub-array and IceCube Upgrade.

Dr. Koskinen investigates the properties of neutrinos, which are the most abundant particles in the known universe after photons. His work explores how neutrinos oscillate quantum mechanically between flavors (electron $$\nu_e$$, muon $$\nu_\mu$$, and tau $$\nu_\tau$$) as they propagate, described as an admixture of mass eigenstates ($$\nu_1$$, $$\nu_2$$, and $$\nu_3$$). This research provides critical insights into physics beyond the Standard Model, as neutrino mass contradicts the Standard Model's prediction of massless neutrinos.

His recent publications demonstrate expertise in analyzing IceCube data across multiple domains including neutrino oscillation parameters, cosmic-ray anisotropy, dark matter searches, and astrophysical neutrino spectra. His work employs advanced statistical methods and machine learning techniques for precision measurements that have important consequences for cosmology and fundamental physics.
