Director, Scintillation Materials Research Center
Ph.D., Washington University, St. Louis
Dr. Melcher earned his bachelor's degree in Physics from Rice University in 1974 and his Ph.D. in Physics from Washington University in St. Louis in 1980 where his dissertation research focused on thermoluminescence phenomena in various materials. Dr. Melcher was a post-doctoral research associate at Caltech for three years working in heavy ion sputtering and planetary science before joining Schlumberger-Doll Research in 1983. While at Schlumberger he led the research effort on radiation detector materials and developed scintillation and semi-conductor detectors for applications in geophysical exploration. As Senior Scientist at Schlumberger, he invented the LSO:Ce scintillator and developed the growth process for single crystals of this material. In 1996 he joined CTI Molecular Imaging where he led the further development of LSO:Ce from the research stage to large-scale commercial manufacturing for use in positron emission tomography (PET). In 2005 Dr. Melcher joined the faculty at the University of Tennessee and soon thereafter founded the Scintillation Materials Research Center where he currently serves as Director. Dr. Melcher has authored or co-authored over 90 technical papers, including two book chapters and several invited review articles. He holds seven U.S. patents and has four pending. He is Associate Editor of the IEEE Transactions on Nuclear Science (TNS) and Editor of the conference proceedings of Inorganic Scintillators and their Applications 2007.
