Professor Stein W. Wallace received his PhD-degree from the Department of Informatics at the University of Bergen in1984. He worked as senior scientist at the Christian Michelsen Institute in Bergen 1981-88, as associate professor at Haugesund Maritime College 1988-90, as professor of operations research at The Norwegian University of Science and Technology 1990-2001, and professor of quantitative logistics at Molde University College from 2001. He is now visiting professor at CUHK. He has held visiting positions at The University of Texas at Austin, University of Washington, Seattle, The University of California at Davis, University of Zurich, University of Iceland, Linköping University, Institut National Polytechnique de Grenoble, France, Columbia University, and IBM Watson Reserch Center in New York.

He chaired COSP- the international organization for stochastic programming - 1992-95, and has held many elected and appointed positions in The Mathematical Programming Society and INFORMS. He serves on the editorial board of INFORMS Journal on Computing, Production Planning & Control, Optimization and Engineering and the stochastic programming e-print series.

Research Interests

His main interest is decision-making under uncertainty. He has published two major books in the field of stochastic programming, namely Stochastic Pro-gramming, (Wiley, with Peter Kall in 1994) and Applications in stochastic pro-gramming, (SIAM/MPS with William Ziemba in 2005). He has also published an operations research textbook in Norwegian, and about 60 scientific articles. His focus is on applications and modeling, and he has worked on applications in fisheries management, oil and gas exploration, portfolio management, electricity markets, telecommunications, and logistics.
