Seokwoo Kim
Hi, my name is Seokwoo Kim and I am a Ph.D. candidate in the department of industrial and management engineering at Pohang University of Science and Technology (POSTECH), under the supervision of Prof. Dong Gu Choi. I am pursuing an academic career upon completion of my doctoral studies.
My research interests lie in the field of Operations Research (OR), with a focus on equilibrium problems under uncertainty, a synthesis of two research areas---optimization under uncertainty and game theory. During my PhD journey, I have been working on robust/bilevel optimization and cooperative game theory in energy markets and service systems.
Currently, I am particularly interested in integrating these methodologies to address the following research directions:
Design of stochastic systems and equilibria through robust/bilevel optimization lens, e.g., markov decision process design, cooperative game design.
Computational methods for cooperative games.

This paper studies a network interdiction game in which a leader and a follower have asymmetric uncertainty models of uncertain network parameters. Using the Wasserstein distance to measure the asymmetricity, we showed that the resulting game admits a single-level distributionally robust optimization counterpart with semi-infinite constraints. Then we designed a mixed-integer semidefinite program to solve this optimization problem and compute the equilibrium of the original game, while also developing a nested Benders decomposition algorithm to improve the computation.
