Overview
Professor Barbeau’s research interests are predominantly in the fields of neutrino and astroparticle physics. His efforts are focused on (but not limited to) three major areas of research: studying the physics of coherent neutrino-nucleus scattering; novel searches for the dark matter in our universe; and searches for zero neutrino double beta decay. The unifying aspect of the work is the common need for new and creative detector development in order to solve some of the “hard” problems in low-background rare-event detection.
