Jeff Martoff (second from left), the recipient of Temple’s first W. M. Keck grant, is also a longtime National Science Foundation-funded principal investigator in the DarkSide search for WIMP dark matter. In 2012, he helped assemble DarkSide 10, an earlier prototype of the current DarkSide WIMP detector, a mile underground at the Laboratorio Nazionale Gran Sasso, a particle physics laboratory near the Gran Sasso mountain in Italy.
