Juan Collar’s work focuses on developing innovative methods for detecting Weakly Interacting Massive Particles (WIMPs) and other hypothetical subatomic particles that could account for dark matter. His research group developed the Chicagoland Observatory for Underground Particle Physics (COUPP) in its quest to detect dark matter. He also develops new methods of neutrino detection, including the smallest neutrino detector made to date.
He co-leads PICO, an experiment that looks for particle dark matter in the Canada-based SNOLAB laboratory, and has also worked in the Coherent Germanium Neutrino Technology (CoGeNT) collaboration and the CERN Axion Solar Telescope. His present emphasis is in neutrino detection.
