Mikhail Korzhik (Korjik) received his diploma in Physics at the Belarus State University in 1981. He got his PhD in 1991 and Doctoral Diploma in 2005 in Nuclear Physics and Optics. Since the beginning of nineties he was deeply involved in research and development of inorganic scintillation materials. He was instrumental in the development of the YAlO3:Ce technology for low energy gamma-rays detection. An important achievement has been the discovery of Pr3+ doped scintillation media and GdAlO3:Ce and LuAlO3:Ce scintillation materials. His study promoted the understanding of scintillation mechanism in many crystals. He took part in the discovery and mass production technology development of the lead tungstate PbWO4 scintillation crystal for high energy physics application, which resulted in the use of this crystal in two ambitious experiments at LHC, CMS and ALICE and an important contribution to the discovery of the Higgs boson. Heis member of the Scientific Advisory Committee of the SCINT cycle of International Conferences dedicated to scintillation materials development.Alexander Gektin received his diploma after graduating at the Physical faculty of Kharkov university. His PhD thesis (1981) was devoted to defects study in halide crystals. He got his DrSci degree in 1990 (Riga, Latvia) when he investigated the influence of high irradiation doses to crystals. During the last two decades he took part as a renowned scintillation material scientist to several international projects like BELLE, BaBar, PiBeta, CMS in high energy physics, GLAST and AGILLE in astrophysics. At the same time he has led several developments for medical imaging (large area SPECT scintillator) and security systems (600 mm long position sensitive detectors).The major part of these technology developments was transferred to different industrial production lines. At the same time he is known as an expert in the study offundamental processes of energy absorption, relaxation and light emission in scintillation materials. He has authored more then 250 publications. He is also an Associated Editor of IEEE Transaction of Nuclear Sciences.
