Shi Nguyen-Kuok - Professor, Doctor of Technical Sciences, Academician of the Russian Academy of Electrical Sciences, Head of Laboratory of Plasma Physics of National Research University "Moscow Power Engineering Institute", Supervisor of Ltd "Technokeramika". Experience of scientific and pedagogical work of Shi Nguyen–Kuok is 22 years, including experience of pedagogical work. Shi Nguyen–Kuok prepared 6 PhD students. Currently, the supervisor of 1 PhD graduate student. Currently, Shi Nguyen–Kuok has 135 publications, including 7 textbooks used in a teaching practice. Shi Nguyen–Kuok developed a theoretical framework for the study of plasma and plasma processes in electrotechnological RF and Arc plasma torches. For the first time he has developed a method of structural modeling of plasma and plasma torches, heat and mass transfer processes and computational procedures allowing to identify the relationship between internal and external (technological and structural) parameters of plasma torches; determine the optimal regime of their agreement with the sources of supply; determine the complex physical processes in RF and Arc plasma torches, their internal and external parameters, heat and mass transfer processes in the plasma jet, near electrode processes, the processes of heat transfer and flow dynamics of solid particles in the plasma, etc.; solve the problems of analysis and structural and parametric synthesis of plasma electrotechnological installations. He developed the theoretical basis of mathematical modeling of electrotechnological plasma processes used in the preparation of lecture courses. In 2006 Shi Nguyen–Kuok received a grant from the President of the Russian Federation "Conducting research by young scientists." In 2012 was awarded by the first place in the competition of manuscripts of scientific literature NRU "MPEI" and received a grant for the publication of a scientific monograph "Basics of mathematical modeling of Low temperature plasma." In 2013 by led of Shi Nguyen–Kuok, RF plasma installation of high power 1000 kW/0.44 MHz for the treatment of refractory particles and for test mode heating materials in the plasma jet, was prepared and released in work (Obninsk, LTD "Technokeramika"). Shi Nguyen–Kuok is a full member of the Russian Academy of Electrical Sciences (from 2015) and the International Academy for System Studies (since 2012).
