Stephen E. Derenzo
Stephen Edward Derenzo (b. December 31, 1942) is a Senior Scientist at the Lawrence Berkeley National Laboratory, Head of the Radiotracer Development and Imaging Technology Department in the Life Sciences Division, and Professor-in-Residence in the Electrical Engineering and Computer Science Department at University of California, Berkeley. Derenzo is an expert in scintillator materials, which are very sensitive detectors of nuclear radiation. They produce a flash of light every time a nuclear particle interacts. The flashes of light can be detected with high-speed photodetectors and the information used to identify the radio-isotopes producing the radiation and how strong they are. In 2001 he won the IEEE Radiation Instrumentation Outstanding Achievement Award. In 2008 he was awarded the Department of Homeland Security Domestic Nuclear Detection Office National/Government Laboratory Contributor award.

Early Life
 Education 

Professor Derenzo was born in Chicago, Illinois. He went to the University of Chicago where he was awarded a bachelor degree for physics in 1963, M.S. in physics in 1965 and a Ph.D. in physics in 1968.

 Early research 

Professor Derenzo began to study Stephen E. Derenzo received the B.S. and Ph.D. degrees in Physics from the University of Chicago in 1963, 1965, and 1968, respectively. He has been with the Lawrence Berkeley National Laboratory since 1968, working first as a Physicist (1968-82) and then as a Senior Scientist (1982- ) affiliated with the Life Sciences Division, Center for Functional Imaging. From 1969-70, he was a Lecturer for the Department of Physics at U.C. Berkeley. In 1980, he joined the faculty of the EECS Department as a Lecturer and has been a Professor-in-Residence since 1988. Prof. Derenzo has authored or co-authored of over 100 journal articles and conference presentations on his area of research interest, specifically, nuclear instrumentation for medical imaging; detectors for Positron Emission Tomography (PET); compact gamma cameras; the development of new, dense, ultra-fast scintillators; and first principle calculations of scintillation mechanisms. He has published two books, interfacing: A Laboratory Approach using the Microcomputer for Instrumentation, Data Analysis, and Control (1990, Prentice-Hall) and Practical Interfacing in the Laboratory: Using a PC for Instrumentation, Data Analysis, and Control (2003, Cambridge University Press). Prof. Derenzo is also the author or co-author of five U.S. patents that are consistent with his research objectives to improve instrumentation for nuclear medical imaging, with particular focus upon the development of new scintillators to accurately detect and measure ionizing radiation. Prof. Derenzo has been the recipient of a number of awards, among which for Distinguished Achievement by a Team in Nuclear Technology for Medical Diagnostics (1984), the LBNL Technology Transfer Excellence Award for PET Instrumentation (1989), the IEEE Nuclear and Plasma Sciences Society Merit Award (1982), and the IEEE Nuclear and Plasma Sciences Society Radiation Instrumentation Outstanding Achievement Award (2001). He is a member of the American Physical Society, and a Fellow of the IEEE for his “contributions to the development of high resolution tomography and the discovery of new scintillators.”

 Recent work 

He currently heads a Homeland Security-funded project that has discovered several new high-performance scintillation materials and hosts the open-access database of scintillation properties. He and his colleagues constructed two pioneering positron emission tomographs (PET) and developed advanced scintillation detectors for PET that provide high spatial resolution, depth-of-interaction information, and compact integrated circuit readout. Since 1988 he has lead a search for new heavy scintillators and currently heads a project for the discovery of scintillation detector materials that uses automation to increase the rate of synthesis and characterization. He has authored or co-authored over 200 technical publications, seven patents, and one textbook. He became an IEEE Fellow in 2000.
