About Me

I am an assistant professor in the Department of Industrial and Systems Engineering (ISysE) at the Korea Advanced Institute of Science and Technology (KAIST). Previously, I was a post-doc in the Discrete Mathematics Group at the Institute for Basic Science (IBS), hosted by Sang-il Oum, and a recipient of the IBS Young Scientist Fellowship (YSF).

I obtained my Ph.D. in the Algorithms, Combinatorics, and Optimization (ACO) program at the Tepper School of Business, Carnegie Mellon University, advised by Gérard Cornuéjols. My thesis won the Gerald L. Thompson Doctoral Dissertation Award for the best Ph.D. thesis in the area of management Science, and I was supported by Henry J. Gailliot Presidential Fellowship. A part of my thesis received Second Place in the INFORMS Optimization Society Best Student Paper Prize Competition 2019.

Research Interests

I am interested in designing algorithms and mathematical programming frameworks for broad areas of optimization spanning continuous, discrete, combinatorial, integer, convex, online, stochastic, robust, and distributionally robust optimization. Currently, I am working on the seamless integration of machine learning and optimization with applications in data-driven decision-making under uncertainty. My latest research projects are on online reinforcement learning theory, stochastic optimization under decision-dependent distributions, first-order methods for constrained optimization, and distributionally robust optimization frameworks.
