Stephen F. Roehrig


Teaching Professor

Prior to joining the Heinz College faculty, Professor Roehrig was a research mathematician at the Coast Guard R&D Center in Groton, Conn., where he focused on analytical and simulation models of Coast Guard missions, and their integration in model management systems.

Professor Roehrig's current research interests include uncertainty management in artificial intelligence, the use of decision models in conjunction with those methods, and the use of numerical methods for logical inference. His recently completed dissertation "Probabilistic and Defeasible Reasoning Using Extended Path Analysis" shows how the statistical technique of path analysis can be reinterpreted as a means of organizing and propagating probabilistic belief in expert systems.

Professor Roehrig received a bachelor's degree in mathematics from Suffolk University, Boston, a master's degree in mathematics from the University of Rhode Island, and a PhD in information systems from the Wharton School, University of Pennsylvania.
