I am a Ph.D. student at University of Tokyo under the supervision of Prof. Satoru Iwata. My research interests are in the area of discrete optimization including combinatorial matrix theory and discrete structures: graphs and matroids. I am also interested in their applications to singal processing, image processing and scientific computing.

Research Areas

  • Discrete structures (graphs and matroids)
  • Combinatorial optimization
  • Combinatorial matrix theory
  • Algebraic algorithms
