Welcome to the Karagiorgi group at Columbia University.

In our experimental particle physics group we are interested in advancing the fundamental understanding of neutrinos and their properties, and 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 are particularly interested in the application 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.


Recent Highlights

Welcome summer 2022 REU students: Our group welcomes Julia Woodward from Amherst College and Mihir Shetty from Fordham University to the Summer 2022 REU program at Nevis Labs! Julia and Mihir will be working with us on searches for new physics with LArTPC detectors.
