Gábor Stépán (pronounced [ˈɡaːbor ˈʃteːpaːn]; born December 13, 1953, in Budapest), Hungarian professor of applied mechanics, member of the Hungarian Academy of Sciences, fellow of the International Academy for Production Engineering (CIRP), fellow of the Society for Industrial and Applied Mathematics (SIAM), former dean of the Faculty of Mechanical Engineering in the Budapest University of Technology and Economics. Won the Széchenyi Prize in 2011, the Thomas K. Caughey Dynamics Award (ASME Applied Mechanics Division) in 2015, and the Delay Systems Lifetime Achievements Award (International Federation of Automatic Control, IFAC) in 2021. His research fields include nonlinear vibrations, delay-differential equations, and stability theory. He was elected as a fellow of the Society for Industrial and Applied Mathematics in 2017, "for contributions to the theory and analysis of delayed dynamical systems and their applications".^[1]

Member of the Society for Industrial and Applied Mathematics since 1992, ASME International since 2013, and Euromech since 2000. Chief editor of Periodica Polytechnica (1993-1994).
