In 1988 he got D.Sc. degree with the thesis \Sensitivity analysis and optimization for problems of stability and vibrations of elastic systems\ from the Academy of Sciences of the USSR in Moscow. In 1991-1992 he visited Denmark as a Guest Professor and gave a lecture course \Vibrations and Stability of Systems Depending on Parameters\ at the Technical University of Denmark (Lyngby) and Aalborg University. Since 1993 A.P.Seyranian is a Leading Researcher and Professor of the Institute of Mechanics, Moscow State Lomonosov University. In 1995 he was elected a Member of The New York Academy of Sciences. In 1998 he became a Member of Editorial Board of the International Journal \Theoretical and Applied Mechanics\ published in Yugoslavia. In 2001 A.P.Seyranian was Coordinator and Lecturer of the course “Stability of Structures. Modern Problems and Unconventional Solutions”, held in International Centre for Mechanical Sciences in Udine (Italy), and Editor of the book “Modern problems of Structural Stability”, 2002, Springer Wien. In 2002 he got the prize of Elsevier Publishers for the best paper published in Journal of Applied Mathematics and Mechanics in 2001. In 2003 he wrote a fundamental monograph on multi-parameter stability problems (with A.A.Mailybaev) published by World Scientific. In 2003 A.P.Seyranian became a member of Editorial Board of International Journal of Structural and Multidisciplinary Optimization. In 2007 A.P.Seyranian as a leader of Moscow group with the partners from Italy, France and Siberia got approval of the INTAS project “Advances of Stability Theory with Mechanical Applications” supported by European Union.
