Stony Brook Experts

In the field of particle physics, Chang Kee Jung is one of the world's leading experts in the study of neutrino oscillations, which occur when a neutrino of one type can change into one of a different type, a phenomenon which could prove critical to understanding the role of antimatter in the origin of the universe.​ Neutrinos ​are similar to the more familiar electron, with one crucial difference: neutrinos do not carry electric charge​. Jung is also an expert in proton decay, a hypothetical form of decay in the Grand Unification Theories in which the proton decays into lighter subatomic particles. He has participated in the T2K Experiment and recently joined the leadership team of the DUNE experiment, aimed at deepening the understanding of the physical universe through the study of neutrinos. ​Lastly, Jung studies and teaches a course about the physics of sports.
