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
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.
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.
