Tamás Koltai has been working as professor of production and operations management at the Department of Management and Business Economics since 1983. For 10 years he also taught operations management at the International Management Center (IMC) in Budapest as adjunct professor. He was a visiting Scholar at the University of Michigan Business School in Ann Arbor for one academic year, and he also worked as a visiting professor at the University of Seville in Spain for three years. He has a master degree in mechanical engineering, a PhD in industrial engineering, and a DSc from the Hungarian Academy of Sciences. He is currently the Dean of the School of Economic and Social Sciences of BME and the Head of the Business Administration and Management Science PhD School. He also works as editor in chief of Periodica Polytechnica Social and Management Sciences series, which is a scientific peer reviewed journal of the School of Management and Social Sciences.
He published several papers in International Journal of Production Economics, Omega, International Journal of Production Research, European Journal of Operational Research, Production and Operations Management and in Computers and Industrial Engineering.
