Welcome to my page

I am a BK21 research professor at the Seoul National University Department of Mathematical Sciences. My research interests lie in the low-dimensional topology, the study on manifolds of dimension $\leq$ 4. In particular, I have been working on the following research topics:

  • Heegaard Floer theory
  • Study of smooth 4-manifolds
  • Knot concordance groups
  • Homology cobordism groups
  • and any other related topics

My research is currently supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Science and ICT (F2018R1C1B6008364).
