Chen's research spans neutrino oscillations, geo neutrino detection, and novel scintillator technologies. He contributed to SNO's discovery of neutrino flavor oscillations and pioneered SNO+'s liquid scintillator design to explore low-energy neutrinos, neutrinoless double beta decay, and Earth's radiogenic heat. His work bridges particle physics and geoscience, seeking answers to questions like neutrino mass and dark matter properties.

His teaching includes advanced courses in mechanics, experimental physics, and astroparticle physics (PHYS 225-844). He has published extensively on neutrino experiments and collaborates internationally on projects like Borexino and SNO+.

• Awards: Gordon & Patricia Gray Chair, CIFAR Senior Fellowship

Chen's grants and collaborations fund detector development, neutrino studies, and outreach. He co-leads SNO+ and advises on low-background environments for dark matter detectors. His lab focuses on scintillator optimization and neutrino detection technologies.
