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 and lighting phosphors. She has 15 awarded patents and more than 100 published papers. Materials under active development include:
Bismuth-loaded plastic scintillator for gamma spectroscopy
