Prof. Leonid Oster has developed mechanisms and applications of exoelectron emission from insulating materials, which permits one to proposed the experimental criteria for systematization of exoelectron emission mechanism
Prof. L.Oster and his coauthors have developed a theory of dose response, the Unified Interaction Model which is capable of explaining all the important features of the supralinearity and sensitization of the various TL glow peaks in LiF:Mg,Ti in a unified mathematical and physical framework
These studies lead Prof. L.Oster to a very well suited to research in this are with many publications and word-wide recognition
Prof. L.Oster was a member in International Professional Commitees. He is serving as a referee in International Scientific Journals, one of Chief Editor for two volumes of Radiation Protection Dosimetry (RPD) and a member of the Editorial Board of RPD
Prof. Leonid Oster is serving as the Head of Physics Unit at Sami Shamoon College of Engineering
