I am a Ph.D. student in the School of Mathematics at University of Minnesota. I have worked on smooth 4-manifolds and geometric topology which are related to symplectic topology. Topics I am familar with: K3 complex surface, (co)homology intersection form, Chern classes, Topological surgery, Seiberg-Witten invariants, Lefschetz fibrations and Mapping class groups.

Recently, I am interested in how exotic-smoothness contributes to the state sum of quantum gravity theory.
