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 160+ articles, 8 books, and 6 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) 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 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
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.
