Tetiana Kozynets, a postdoctoral researcher at the University of Liverpool, was awarded a 2025 Global Neutrino Network (GNN) Dissertation Prize. This year, Kozynets was one of three postdoctoral candidates who were awarded the prize. The winners were announced at the 2026 GNN meeting this week in Amsterdam.
The GNN dissertation prize recognizes young postdoctoral candidates who have written an outstanding thesis and made significant contributions to neutrino astronomy. Primary criteria of the selection are the scientific quality, the didactics, and the form of the thesis.
Kozynets conducted her PhD work at the University of Copenhagen under Professor Jason Koskinen. Her thesis, “Atmospheric neutrino oscillations in IceCube-DeepCore within and beyond the unitary framework,” investigated the systematic uncertainties in DeepCore and simulated atmospheric neutrino oscillations with the IceCube Upgrade. Kozynets was recognized for her key contributions when she was awarded an IceCube Impact Award in 2023.
