I was educated in special mathematical class of Rostov High school #5, in school period took part in many scientific Olympiads and often had success. Then I continued "Olympiad activity" as an organized, member of jury comity and mathematical facultative lessons provider. I studied on Mechanical and Mathematical faculty of Rostov State University (1971–76); first time on mechanical department and from 3 year on mathematical department where Professor Igor Simonenko was my scientific supervisor. At the end of third year I had prepared scientific article about multidimensional discreet multiplicators. Then I followed my professor and switched to investigation of Markov type estimations for quasi-polynomials. My PhD thesis (1980) also investigates such type estimations and their applications to mathematical physics problems. I very actively participated in mathematical and applied investigations in ocean acoustics, which took place in Rostov University (82–91). A significant part of this work consisted in extracting of a mathematical setting from engineer field balancing mathematical precision, rationality and possibility to interpret result. And I liked this type of work. I taught students in Rostov State University (1979–97) mostly on Mechanical and Mathematical Faculty. Publications 1990–97 reflect mathematical part of my gyro-acoustical investigation. From 1997 I work in Information Technology Industry. I take part in innovations and development new technology solutions prepare reasonable models of practical phenomena and investigate them.
