John Hooker is
University Professor of Operations Research and T. Jerome Holleran Professor of
Business Ethics and Social Responsibility, Emeritus, at Carnegie Mellon
University. He has also held several visiting posts, most recently at the
London School of Economics and the State University of Campinas, Brazil.
He holds doctoral degrees in philosophy and operations research.
Professor Hooker has published 200+ articles, 9 books, and 6 edited volumes in operations research, constraint programming, AI, formal logic, business ethics, ethics of AI, cross-cultural management, philosophy, and music theory. He is a Fellow of the Institute for Operations Research and the Management Sciences (INFORMS) as well as recipient of the INFORMS Computing Society Prize and the INFORMS Khachiyan Prize for lifetime achievements in optimization. He served as chair of the INFORMS Computing Society and in numerous editorial positions. He is equally active in the constraint programming community, where he has chaired conferences, served on the Executive Committee of the Association for Constraint Programming (ACP), and received the biennial ACP Research Excellence Award.
He is a pioneer in the integration of optimization and constraint programming technologies, having written the first book and co-chaired the first conference on the subject. OR/CP integration is now a key element of leading software packages. Professor Hooker also introduced logic-based Benders decomposition, which is based on a concept of inference duality. It can reduce solution times by orders of magnitude and has found a wide variety of applications. He was the first to observe the phase transition phenomenon in satisfiability problems. More recently, he and T. Hadžić introduced decision diagrams as an optimization method, and several investigators are now pursuing this line of research.
Professor Hooker’s interests in business ethics and cross-cultural management are reflected in his books Business Ethics as Rational Choice, Working across Cultures, Taking Ethics Seriously, and Advanced Introduction to Business Ethics. He is founding editor-in-chief of the Journal of Business Ethics Education, the only academic journal dedicated to the topic, and he co-organized four conferences on international corporate responsibility. He has lived and worked in Australia, Brazil, China (twice), Denmark, India (twice), Qatar, Turkey, the United Kingdom, the United States, and Zimbabwe, and has extensive experience in France, Germany, Ireland, Italy, and Mexico. In addition, he has written a number of musical compositions for piano, chamber groups, and chorus.
Professor Hooker received a Distinguished Academic Leadership Award for his direction and reorganization of the Tepper School's undergraduate business administration program. He was recognized with an Award for Sustained Teaching Excellence (one of only two awarded) and the Gerald Thompson Excellence in the Classroom Award.
