Professor
Profile
I pursue research on Discrete Optimization, Graph Theory and Computational Complexity.Especially, my research interests include matroid structure and submodularlity in discrete optimization problems, good characterizations related to packing problems in graphs, and mathematical programming approaches to proving limits of computation. Furthermore, I pursue research on application of these theories to urban/social system design.
