EDUCATION
Massachusetts Institute of Technology
Cambridge, MA
 Ph.D. in Operations Research, Operations Research Center, 1999.
 Dissertation Topic: Motivated by applied problems in supply chain management, the
dissertation examines generalized, multi-commodity network flow problems with
piecewise linear cost functions. We examine the theoretical and practical implications
of various modeling techniques. In particular, we develop and solve a model for
operating a merge-in-transit distribution system. This model is implemented as a largescale mixed-integer program that requires advanced algorithmic techniques to solve.
This work was advised by Thomas L. Magnanti.
