I'm a mathematician, and a part-time celebrity in South Korea. Currently, I'm a member at the Institute for Advanced Study.

I specialize in the investigation of geometric structures through their invariants. My latest project focuses on expanding the scope of motivic homotopy theory by removing the assumption that the affine line is contractible (video). This framework is aimed to enable applying motivic homotopy theory to cohomology theories that were previously deemed inaccessible, such as prismatic cohomology. During my doctoral studies, I studied intersection theory and its generalizations, such as algebraic cobordism, using derived algebraic geometry (video). Beyond pure mathematics, I have investigated topological structures arising in physics. In particular, in collaboration with physicists, we have investigated the topological stability and classification of vortex-link structures formed from non-Abelian vortices that could arise in, for example, liquid crystals and Bose–Einstein condesates (article).
