I’m a Ph.D. student at the Department of Mathematical Sciences in KAIST and the Discrete Mathematics Group (DIMAG) in the Institute for Basic Science (IBS). My supervisor is Sang-il Oum

My research interests are about graphs, matroids, and delta-matroids, especially, vertex-minors and pivot-minors of graphs, and structural properties of a minor-closed class of matroids and delta-matroids.
