Ben is an experimental nuclear-structure physicist. His main areas of interest are the single-particle structure of nuclei and its connection to the rate of decay of neutrinoless double-beta decay candidates, the evolution of trends in nuclear excitations with neutron excess, and weak-binding phenomena in nuclei. He carries out experiments at various laboratories around the world, leading several research programs. Ben has a keen interest in nuclear instrumentation, including novel charged-particle spectrometers of which he is currently leading an initiative to build one at the Facility for Rare Isotope Beams at Michigan State University. Ben joined the Physics Division in 2013.
