Christopher W. Zobel
Christopher Zobel is a member of the Department of Business Information Technology at Virginia Tech. His academic training is in mathematics and systems engineering, and his research focuses on developing analytic techniques to improve environmental decision making and disaster/crisis operations management. He has significant experience with multi-objective and multi-stakeholder decision problems, as well as with stochastic optimization, and simulation-optimization techniques. He is particularly interested in the quantitative analysis of multi-dimensional concepts such as disaster resilience, which have not only physical and economic characteristics but also social and organizational dimensions. In this context, his primary focus is on more clearly identifying and leveraging the trade-offs inherent in decisions that affect resilient behavior.
