1998-2001 Director of Intelligent Systems Research Center in Kiev, Ukraine sponsored by the USAID. Organized over 30 technical workshops in 10 regions of Ukraine
1995-2000 – Full-time technical consultant to USAID/FMI/PADCO/TRG/Chemonics in Ukraine (Kiev, Lviv, Donetsk), Russia (Irkutsk), Moldova (Cisinau) and Kazakhstan (Alma-Aty). Participated in 6 technical assistance projects in CIS countries financed by USAID with the total budget of 5 mln USD.
1993-1995 Visiting researcher in German Aerospace Research Establishment (DLR), Institute of Material Research, Cologne, Germany.
1991-1992 Personal R&D work in collaboration with the Paton Welding Insitute of the National Academy of Sciences of Ukraine, Kiev on numerical simulation and life prediction of critical elements of Mir orbital station. Fretting fatigue crash predictions necessitated in-situ replacement and reinforcement of bearing components of the energy system of solar batteries.
