Dr. Giorgio Gratta

Biography

Giorgio Gratta is a Ray Lyman Wilbur Professor in Physics at Stanford University with a research focus on experimental particle physics. His career began with experiments at particle colliders, later concentrating on neutrinos and their properties. Gratta's landmark experiments have demonstrated phenomena such as neutrino flavor mixing and oscillations using artificial neutrinos. He has established the finite nature of neutrino masses and contributed significantly to Earth sciences through experiments detecting neutrinos from nuclear reactors. Moreover, Gratta has led the development of liquid xenon detectors aimed at discovering neutrinoless double beta decay, an exotic nuclear decay which could alter the understanding of quantum aspects of neutrinos and help explain the matter-antimatter asymmetry in the universe. Currently, he is the scientific leader of large-scale experimental collaborations worldwide and is studying new long-range interactions or anomalous gravitational behavior at micro-distances. His work employs advanced techniques like optical levitation and neutron scattering to explore the properties of nanostructured materials.
