Dr. Sperber is a theoretical physicist. In recent years, he focused attention on the study of the liquid-gas phase transition in nuclei and on the two fluid model of nuclei using sophisticated methods of statistical mechanics.
Similar methods are applicable to the investigation of other multiphase phenomena.
Also, he was a former Visiting Research Professor in Darmstadt, Germany. Who's Who in Science and Technology, as well as in fifteen other biographical publications. He holds Masters degrees from The Hebrew University in Jerusalem and Princeton University, and has a Ph.D. Degree from Princeton University. Dr. Sperber's research covers many areas of theoretical nuclear physics focusing on the study of hot nuclei and hot nuclei matte. Theory of nuclear fission.
