Welcome to the Karagiorgi group at Columbia University.
We are an experimental particle physics group interested in advancing the fundamental understanding of neutrinos and their properties. We are also interested in searching for new physics beyond the Standard Model, which may be accessible through neutrino experiments and the study of rare particle processes. In doing so, we continually explore applications of novel instrumentation and data processing techniques for particle imaging detectors.
Our group includes a number of postdoctoral researchers, PhD students, and undergraduate students. We also frequently collaborate with other faculty and researchers at Columbia, as well as scientists and engineers all over the world through our participation in major international particle physics experiments, based primarily at Fermi U.S. National Accelerator Laboratory.
GRAMS selected for NASA APRA funding! Our group will be funded by NASA APRA to construct the LArTPC readout system for the GRAMS prototype balloon flight planned for 2025-26. Find out more about GRAMS here.
