I am a graduate student in the Department of Physics at Hanyang University, working with Prof. Moon Jip Park on theoretical condensed matter physics.

My research focuses on topological phases, quantum geometry, and magnetoelectric responses in correlated and van der Waals systems. I am particularly interested in microscopic modeling and symmetry-based theory for emergent electronic and magnetic phenomena — see the research page for details.

Beyond physics, I write here about research life, the PhD journey, and everything in between on the blog.
