Head of Department of Computational mathematics of Tbilisi State University. Supervised the Institute scientific-research works, concerning investigation and realization of different problems of mathematical physics and mechanics of continuum media. During that period I investigated problems of the theory of elastic mixtures, nonlocal-in-time problems for some equations of mathematical physics; mathematical models for computation of thermoelastic state of some energetic plants (TOKAMAK-15) (The works were carried out together with the colleagues of I. V. Kurchatov Atomic Energy Institute, Moscow).
Deputy Director of I. Vekua Institute of Applied Mathematics. Supervised the Institute scientific-research works in computational mathematics, magnetic hydro-dynamics, meteorology, shell-theory. During that period investigated and developed methods of decomposition for nonstationary problems of mathematical physics; the works on thermo-elastic state of some energetic plants were carried out together with I. V. Kurchatov AtomicEnergy Institute, Moscow).
Head of the department of Numerical Methods of I. Vekua Institute of Applied Mathematics. Supervised the scientific work of the department in shell theory, meteorology, ecology, magnetic hydro-dynamics, computation and optimization of gas pipelines; took part, together with the scientists of Taganrog Radio-Technic Institute, in special works concerning modelling of computing devices for aircrafts; I participated in the investigation of computing methods for problems of plasm physics too (together with colleagues of USSR Academy Institute of Applied Mathematics and Sukhumi Physical-Technical Institute).
Probationer of the Laboratory of Numerical Analysis in the Paris University (science supervisor - acad., prof. J.-L. Lions).
Senior scientific worker at I. Vekua Institute of Applied Mathematics; investigation of the variational-differentional schemes for problems of I. Vekua theory of shells. Investigation of the economical-differentional schemes for solution of problems of mathematical physics.
Junior research worker of A. Razmadze Institute of Mathematics, Georgian Academy of Sciences. Investigation of stability and convergence of finite differentional schemes for some nonlinear parabolic equations; investigation of local one-dimensional schemes for parabolic equations of 2m-order.
