Hooker is Professor of Operations Research and T. Jerome Holleran Professor
of Business Ethics and Social Responsibility 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
Hooker has published 150+ articles, 8 books, and 5 edited volumes in
operations research, constraint programming, ethics, cross-cultural
management, and music theory. He is a Fellow of the Institute for
Operations Research and the Management Sciences (INFORMS) and recipient the
INFORMS Computing Society Prize. 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 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
introduced decision diagrams as an optimization method (2006), and several
investigators are now pursuing this line of research.
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.
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.
