The Colorado State University professor of physics studies the fundamental matter particles known as neutrinos, and an exceedingly rare instance of radioactive decay in which neutrinos-otherwise present in such decays-are nowhere to be found.  Determining features of the elusive particle known as a neutrino-through the observation of an extremely rare nuclear process called neutrinoless double-beta decay (The inclusion of short-range interactions in models of neutrinoless double-beta decay could impact the interpretation of experimental searches for the elusive decay.  The occasional decay of neutrons into dark matter particles could solve a long-standing discrepancy in neutron decay experiments.  The U.S. Department of Energy has approved funding and start of construction for the SuperCDMS SNOLAB experiment, which will begin operations in the early 2020s to hunt for hypothetical dark matter particles called weakly interacting massive particles, or WIMPs.  Thanks to low-noise superconducting quantum amplifiers invented at the University of California, Berkeley, physicists are now embarking on the most sensitive search yet for axions, one of today's top candidates for dark matter.
