Professor of University of Nice-Sofia Antipolis (France). Author of over 100 scientific articles and one monograph. M.S., Moscow Physical-Technical Institute (MFTI, 1977). Ph.D. (Geomechanics of Oceanic Subduction), Institute of Oceanology, USSR Acad. Sci. (1981). Researcher at Moscow State University and the Geosphaera Research Center, USSR Acad. Sci. and investigated the geomechanics of lithospheric convergence, rifting , and spreading zones (1981-1993). Laureate of the USSR National Youth Prize in Science and Technology (1985). Visiting Professor at the National Central University of Taiwan (1991-1993); proposed and developed the geomechanical model showing the complex three-dimensional collision in this region.  Professor at the University of Montpellier  (France) (1993-1996); developed models of continental collision and rapid exhumation of sedimentary and continental crust materials subducted to large depths. Since 1996, Professor of Geomechanics and Geology at the University of Nice-Sophia Antipolis (France). He performed experimental and numerical modeling of thermo-mechanical processes in the lithosphere, crust and sedimentary cover of collision belts. In 2001, he co-founded Geo-FracNet consortium for collaborations between the Universities of Montpellier and Nice-Sophia Antipolis and Industry, including Shell (Hague and Houston), Total, Eni-Agip, and Entreprise Oil. Today he is Director for Science of Geo-FracNet, a multidisciplinary research network, uniting university research in Montpellier, Nice, Paris and Zurich. The consortium provides funds for research projects aimed at tectonical and mechanical analysis and prediction of reservoir fracturing; it is a platform for discussion between scientists from academic organizations and oil companies. In 2017, he was awarded the Grand Prix of the French Academy of Sciences. From 2018, he is Professeur des Universit é s de With lasse Exceptionnelle, which is the highest professorial rank in France.
