Arthur McDonald is a particle physicist whose current work seeks to further our understanding of neutrinos.

The addition of tellurium to the scintillator in the newly configured SNO+ detector should allow the study of neutrinoless double beta decay, giving important insights into whether neutrinos serve as their own antiparticles and perhaps providing a measure of the absolute mass of neutrinos. McDonald is also participating in the DEAP-3600 experiment, a new argon-based dark matter detector to be constructed in SNOLAB and predicted to be 10 times more sensitive than current measurements.
