Satoru Iwata

My primary research interests are in the areas of mathematical programming. I have been working on design and analysis of efficient algorithms for discrete optimization concerning matroids and submodular functions. I am also interested in applications of discrete optimization techniques to algebraic/numerical computation that arises in systems analysis and control.
