Gerald Entine,  Ph.D. , President

     Dr. Entine received his B.SC. in Physics/Biophysics and M.A. in Physics from the University of Pennsylvania. He received his Ph.D. in physics from the University of California at Berkeley under the direction of two Nobel Laureates - Dr. Melvin Calvin and Dr. Owen Chamberlain.  His thesis topic was the detection of instantaneous changes in the nerve membrane during the action potential.  As an undergraduate at the University of Pennsylvania, he developed a microspectro-photometer to measure in situ the photopigments of individual rods and cones of the retina.  During his schooling he published a substantial number of technical papers in the fields of instrumentation, biophysics and chemistry.

     Dr. Entine then joined Tyco Laboratories, a high technology research center in Boston, and conducted studies in semiconductor sensors. In 1971, he began development work on an infrared photosensor, which became the first practical device made from CdTe.  This patented device was carried from the conceptual stage to a successful prototype stage in less than nine months, and was tested by the Air Force as an aircraft engine fire detector.

     In 1972, he turned his attention to a new, solid state nuclear detector made of CdTe, and assumed responsibility for all aspects of the work, including crystal growth, detector fabrication, and marketing activities.  This technology provided the basis for Radiation Monitoring Devices, Inc., which Dr. Entine spun off from Mobil Tyco Solar Energy Corp. in August 1974, and has led to a wide variety of advanced nuclear instruments for medicine, power plants, and industry.

     Since 1974, Dr. Entine has spent his time and effort guiding RMD as its founder and president. Dr. Entine continues to be involved in research, and has been the Principal Investigator on numerous research contracts and grants funded both privately and by federal agencies. These programs included the development of a portable cardiac ventricular function monitor with the Nuclear Medicine Department of Massachusetts General Hospital, research on new, nuclear techniques to measure peripheral blood circulation in diabetics with State University of New York in Buffalo, improvements on cerebral blood flow measuring systems with solid state sensors at New York University and Bowman Gray School of Medicine, as well as other smaller programs with Yale, Massachusetts General Hospital Department of Cardiology, and the West Roxbury Veterans Hospital. These programs have resulted in technical papers and presentations, and in several cases, extensive clinical programs. Dr. Entine is currently an Adjunct Research Assistant Professor in the Department of Neurology at the Bowman Gray School of Medicine.

     Dr. Entine has presented contributed and invited papers on semiconductor devices both here and abroad, and serves as a technical reviewer for grants and articles. His publications include works in Physics and Instrumentation (48), Basic Chemistry (22) and Medicine and Biophysics (51).
