**Candidate of Physics and Mathematics,**

**associate professor of Information Science and Higher Mathematics Department at Ostrogradsky Kremenchug State Univerity.**

**Was born (1951) and raised in Kremenchug, Ukraine. During his school years took interest in electrical and radio engineering, physics, math, lathe and bench work.**

In 1968 graduated from school with distinction and entered the Moscow State University, where he attended lectures of prof. Ilyin V.A. (Higher Math), academician Leontovich M.A. (Electrodynamics), docent Krivchenkov V.D. (Quantum Mechanics), academician Lifshitz I.M. (Solid-State Physics), prof. Bonch-Bruevich V.L. (Theory of Semiconductors), etc. In the course of his junior and senior years he won the Lomonosov Scholarship.

In 1974 he graduated from univesity with distinction and began his postgraduate study at the Department of Semiconductor Physics (1974 - 1977). Under the supervision of Professor V.S.Vavilov he wrote a dissertation on experimental and theoretical research of hopping conductivity in submillimeter-wave region of spectrum.

After the defence of the dissertation in 1981, he left for the Baikonur to lecture at the branch establishment of MAI "Voskhod" (Leninsk). For 4 month he went through the internship at the Physics Department of MAI, guided by prof. Alekseev B.V.

For a long time period since he had left Moscow he maintained his university relations, regularly consulted with Mironov A.G. - one of the leading theorists of Bonch-Bruevich's group, giving for Mironov's consideration all his "boundary" works of mathematical and theoretical kinds, gave lectures at the Department's common and theoretical seminars.

As soon as he'd moved from the refined university enviroment to the provinces, he realized, that it's possible to be engaged in true science away from metropoleis only if focusing on those promising researches, which run years or even decades ahead of contemporary world science trends.

After he'd proceeded to lead his own independent scientific effort, he kept on lecturing. For different time periods, he taught Higher Math, Theory of Probability, General Physics, Theoretical Physics and its special chapters. All the while he carried on self-education (Group Theory, Functional Analysis, Numerical Analysis, Laser Physics, Holography, Neural Networks, Mathematical Modelling, Ill-posed Problems, Pattern Recognition, Deterministic Chaos, Fractals, History of Maths and Physics, etc.).

In 1981 with the reference of Vavilov V.S. he was engaged to work at Samara Branch of Academy of Sciences' Physical Institute (branch was recently created on academician Basov's initiative), where he started to work on thermovision - new scientifical trend, which combined achievements of Semiconductor Physics, Optics, Mathematical Theory of Measuring and Digital Image Processing and its applications to Nondestructive Thermal Testing. In connection with that he contracted with Azovsky Mechano-Optical Factory, actively collaborated with pro-rector of Tomsk Polytechnical Institute Vavilov V.P. Inspired by Vavilov's advice, he entered doctoral degree program (1991-1995) at Lykov ITMO in Minsk. After finishing program, by force of circumstances he gave up science (then it seemed to him, that was for good), and for 4 years he was in private practice, where, as an insider, he was able to study economical mechanisms of functioning and interaction of business and state under conditions of the real market.

Several times he went abroad (in 1984 - Dresden, Germany, in 1985 - Jena, Germany, in 1992 - Paris, France - scientific missions; 1998, Germany - business trip).

About 10 years ago he resumed lecturing, first in Minsk, Belarus, then in Kremenchug, Ukraine, where he returned to in 2003. There he participated in establishing the Economical Cybernetics Department at Kremenchug Institute of Dnepropetrovsk University of Economics and Law, and for 2 years was at the head of the department (2003-2005). That induced him to go deeper into the variety of subjects, adjancent to Economics, Cybernetics and Information Science (System Analysis, Electronic Commerce, Computer Networks, Discrete Mathematics,

Logic, etc.) Meanwhile he obtained a degree in Economics of Enterprise.

He notes, that he doesn't think of himself as a "pure" mathematician or theoretical physicist, however, he always seeks to gain a complete understanding of basic ideas and axiomatics of diverse mathematical (and some other) theories and to apply the results of this "boundary" analysis to his own research activities. What he learned not only from the history of science, but at first hand, is that there always was a problem to make the scientific community admit something that is boundary and doesn't fully belong to any of the related fields of knowledge. More than 15 years ago he wrote a doctoral dissertation on identification of object's and system's states in extremely sensitive realization of active nondestructive thermal testing. Dissertation committee members - Vavilov V.P., Doctor of Technical Sciences (Nondestructive Thermal Testing); Pytiev Yu.P., Doctor of Physical and Mathematical Sciences (Mathematical Theory of Measuring); Glasko V.B., (Inverse Problems of Mathematical Physics), all of them being experts in their own field, appreciated the work in whole, but said they couldn't substantially criticize parts of work that were outside their competence.

Author thinks, that results of this dissertation are still relevant and frontier, since they contain new methodological approaches to mathematical statement and solving algorithms of complex systems identification problems. Their practical implementation, owing to the great amount of computing required, has only recently become possible. There have also been developed conditions for the extending of the range, where aforementioned methodology can be applied, including problems of modelling of socio-economical, ecologocal and other badly formalized systems.

His academic interests now basically are in the fields of scientific knowledge that are not fully established yet, i.e. Complex Systems Theory, Constructivist Mathematics, Dynamic Chaos, Fractals, Quantum Econophysics.

Unfortunately, for various reasons results of his scientifical researches haven't been effectively promoted, hence there are relatively few (approximately 70) published works, 17 of them were published during the last year (2009).

For the last few years he has been collaborating with theoretical physicist Soloviev V.N., Doctor of Physical and Mathematical Sciences, head of the Economical Cybernetics Department at Khmelnitsky National University of Cherkassy. Among the results of this collaboration is publication of their collective monograph "Relativistic quantum econophysics – new paradigms in complex system modelling", it's english version available in the arXiv:0907.1142v1 [physics.soc-ph] 7 Jul 2009.
