Robert Nau is a Professor Emeritus of Business Administration in the Fuqua School of Business, Duke University. He received his Ph. D. in Operations Research from the University of California at Berkeley. Professor Nau is an internationally known authority on mathematical models of decision-making under uncertainty. His research has been supported by the National Science Foundation, and his papers have been published in journals such as Operations Research, Management Science, Annals of Statistics, Journal of Economic Theory, and the International Journal of Game Theory. He was a co-recipient of the Decision Analysis Society Best Publication Award. One of the themes in Professor Nau's research is that models of rational decision-making in various fields are linked by a single unifying principle, namely the principle of no-arbitrage, i. e. , avoiding sure loss at the hands of a competitor. This principle is central to modern finance theory, but it can also be shown to be the fundamental rationality concept that underlies Bayesian statistics, decision analysis, and game theory. Professor Nau has taught the core MBA courses on Decision Models and Statistics in several programs, and he developed an MBA elective course on Forecasting, which he has taught throughout his career. He also teaches a course on Rational Choice Theory in the Ph. D. program that draws students from other departments and schools at Duke University.
