My research interests are on developing theory and algorithms to solve real-world problems. In particular, I have been working on solving optimization problems on networks. Related topics include

  • Combinatorial Optimization and Graph Algorithms
  • Discrete Mathematics and Combinatorics
  • Mathematical modeling
  • Operations Research/Management Sciences
  • Machine Learning
  • Combinatorial Matrix Theory
In the right figure, one can see specific examples arising from
  • Online advertising over a social network
  • Designing an energy-efficient sensor network
