Tuncer Ören is a professor emeritus of computer science at the School of Electrical Engineering and Computer Science of the University of Ottawa, Canada. He has been involved with simulation since 1965. Dr. Ören's Ph.D. is in Systems Engineering from the University of Arizona, Tucson, AZ (1971). His basic education is from Galatasaray Lisesi, a high school founded in his native Istanbul in 1481 and in Mechanical Engineering at the Technical University of Istanbul (1960). His research interests include advancing methodologies for modeling and simulation; agent-directed simulation; agents for cognitive and emotive simulations especially for conflict management training (including representations of human personality, understanding, misunderstanding, emotions, and anger mechanisms); reliability, QA, failure avoidance, ethics; as well as body of knowledge and terminology of modelling and simulation. He has well over 500 publications, including 46 books and proceedings –some translated in Chinese, German and Turkish. He has contributed to over 500 conferences and seminars held in 40 countries. He has been a keynote or invited speaker, or honorary chair in about half of them. Dr. Ören has been recognized, by IBM Canada, as a pioneer of computing in Canada where he has been also the Founding Chair of the Executive Committee of the Chairmen of the Canadian Computer Science Departments. He received “Information Age Award” from the Turkish Ministry of Culture and an “Honor Award” from the (Turkish) Language Association (2012). Dr. Ören is a Fellow of SCS (2016) and was inducted to “SCS Modeling and Simulation Hall of Fame” (Lifetime Achievement Award) in 2011. Some of his recent distinctions include the Golden Award of Excellence from the International Institute for Advanced Studies in Systems Research and Cybernetics (2018); SCS McLeod Founder's Award for Distinguished Service to the Profession (2017); and a book edited by Prof. Levent Yilmaz: Concepts and Methodologies for Modeling and Simulation: A Tribute to Tuncer Ören. Springer (2015).
