BA, Rice University, 1964

MS, Texas A&M University, 1965

PhD, Purdue University, 1968


Dr. Dupree is an expert in the detection, measurement, and analysis of nuclear radiation, with emphasis on the development and use of radiation transport techniques for application to radiation shielding, effects, criticality, and safety.  He has extensive experience in arms control, treaty verification, nuclear nonproliferation and international safeguards.  He was manager of the group that developed the radiation detection equipment used to support verification of the Intermediate Nuclear Forces and START treaties.  He was a technical consultant to the US delegation to the Joint Compliance and Implementation Commission for the START treaty and helped negotiate the protocol for use of the radiation detection equipment permitted under that treaty.  He has worked with the US Department of Energy in joint projects with scientists at the Russian nuclear institutes in the areas of nuclear nonproliferation and nuclear materials management.  He is the Assistant Technical Editor of the Journal of Nuclear Materials Management.
