I am a post-doctoral researcher in the Discrete Mathematics Group at the Institute for Basic Science (IBS), South Korea. I obtained my Ph.D. in the Algorithms, Combinatorics, and Optimization (ACO) program at the Tepper School of Business, Carnegie Mellon University. I am very fortunate to be advised by Gérard Cornuéjols.
