Nerine Cherepy earned a Ph.D. in Physical Chemistry from the University of California, Berkeley. After postdoctoral work at the University of California, Santa Cruz, she joined Lawrence Livermore National Laboratory. Since 2005, she has worked on the development new light-emitting materials, including single crystals, transparent ceramics and plastics, for various uses in ionizing radiation detection, new imaging screens, lighting phosphors and laser gain media. These efforts involve device integration of new light-emitting materials for gamma spectroscopy, X-ray and neutron imaging, as well as lighting and laser applications. She has 17 awarded patents and more than 150 published papers. Materials development includes:
