Invented the unique ‘quasi-map’ invariants and their wall-crossing formulas to explain the various relationships between the algebraic geometry invariant of space and the holomorphic symplectic geometry invariants.
Developed various principles (late 1990s) to solve the conundrums of mirror symmetry that were raised in the early 1990s, accomplishing pioneering achievements in the Gromov-Witten theory, and published his theses in the Acta Mathematica and Annals of Mathematic, which are the representative academic journals in mathematics.
Selected as an invited lecturer in the algebraic geometry area at the 2014 International Congress of Mathematicians (August 13~21), which is considered the Olympics of Mathematics.
