I am an Assistant Professor at SUNY Korea. Previously, I was a Research Fellow at the Korea Institute for Advanced Study (KIAS) and the Applied Algebra and Optimization Research Center (AORC) at Sungkyunkwan University. My research interests lie in Graph Theory, Matroid Theory, and Combinatorial Optimization, with a focus on structural and algorithmic problems in graphs and matroids.
