John Hooker is Professor of Operations Research and T. Jerome Holleran Professor of Business Ethics and Social Responsibility at Carnegie Mellon University.  He joined the Tepper School of Business at CMU in 1984 and has since 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 170+ articles, 8 books, and 5 edited volumes in operations research, constraint programming, ethics, cross-cultural management, and music theory.  He is an INFORMS Fellow and recipient of the INFORMS Computing Society Prize.  He has served on several editorial boards, including two decades as an area editor for INFORMS Journal on Computing, and was elected chair of the INFORMS Computing Society.  He is equally active in the constraint programming community, where he has chaired conferences and workshops and served on the Executive Committee of the Association for Constraint Programming.
He is a pioneer in the integration of optimization and constraint programming technologies, having written the first book (2000) and co-chaired the first conference on the subject (1995).  OR/CP integration is now an active research field and provides the basis for leading software packages like IBM's OPL Studio and the popular award-winning solver SCIP.  Professor Hooker also introduced logic-based Benders decomposition (1995, 2000), 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 (1990) and introduced the concept of a backdoor set (1992).  More recently, he and T. Hadžić adapted decision diagrams to optimization (2006), 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, and Taking Ethics Seriously.  He is founding editor-in-chief of the Journal of Business Ethics Education and co-organized four conferences on international corporate responsibility.  He has lived and worked in Australia, Brazil, China, Denmark, India, Qatar, Turkey, the United Kingdom, the United States, and Zimbabwe, and has extensive experience in Germany 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 in 2001 for his direction and reorganization of the Tepper School's undergraduate business administration program. He was recognized with an Award for Sustained Teaching Excellence in 2009 and the Gerald Thompson Excellence in the Classroom Award in 2016.
