I am an M.S. Student, Graduate School of Industrial & Systems Engineering, KAIST, advised by Prof. Jinkyoo Park in the System Intelligence Lab.

I received my B.S. in Industrial Engineering from Hanyang University. I worked with Prof. Jaewook Song at the Financial Innovation & AnalytiX - FINX Lab, focusing on graph-structured problems, particularly algorithm design and problem formulation. During an internship at SPACEMAP, I developed satellite collision probability algorithms and shortest-path algorithms for satellite communications.

I am broadly interested in leveraging Machine Learning for Combinatorial Optimization (ML4CO) to solve complex, real-world problems, with a particular focus on integrating ML with Mixed-Integer Linear Programming (MILP). Currently, my research centers on exploring and developing discrete diffusion models to tackle these optimization challenges.
