Dr. of Science, Academician of the National Academy of Sciences of Kazakhstan. He received the Candidate of Science degree in differential equations from the Kazakhstan Academy of Sciences in 1968 and Doctor of Science degree in Mathematical Physics from the Institute of Thermophysics, Siberian Branch of the Russian Academy of Sciences, Novosibirsk, in 1990. From 1991 to 1994 he was Professor and Head of the Laboratory of Mathematical Physics Equations at the Institute of Mathematics of the Kazakhstan Academy of Sciences and then deputy director for Science of this Institute. In 1994 S.N. Kharin got the academic rank of Associate Member of the National Academy of Sciences of the Republic of Kazakhstan and was appointed the Head of the Department of Physics and Mathematics of the academy. From 1996 to 2001 he worked as a Visiting Professor of GIK Institute of Engineering Sciences and Technology (Topi, Pakistan). In 1998 he was elected a Foreign Fellow of Pakistan Academy of Sciences. In 2001 Prof. S.N. Kharin was invited by the University of the West of England (Bristol, UK) for teaching and research as a Visiting Professor and was employed there up to 2003. In 2003 he returned back to Pakistan and was a Visiting Professor of GIKI until 2005. From 2005 he is Professor of ISE at KBTU. Prof. S.N. Kharin is well-known specialist in mathematical modelling of phenomena in electrical contacts and low temperature plasma. He is the author of the thermal theory of bridge erosion in electrical contacts, the mathematical model of the influence of thermoelectric effects on contact heating, the model of the transition from metallic arc phase to gaseous arc phase, models of transformation of arc-to-glow discharge. He discovered and explained mathematically the thermo-capillary mechanism of arc erosion in electrical contacts, created the mathematical model of contact floating in vacuum circuit breakers, described mathematically dynamics of contact blow-open and many other electrical phenomena.
He published about 300 research papers, including 3 books and 12 patents. He was awarded the Gold Medal of the USSR Exhibition and the Honorary Medal “Inventor of the USSR” for the elaboration of the plug electrical connector SP – 063.
