I am currently an associate professor at the Morningside Center of Mathematics, Chinese Academy of Sciences. I am doing research on algebraic geometry, symplectic geometry and mathematical physics with special emphasis on higher dimensional gauge theory. I have been studying Donaldson-Thomas type theory on Calabi-Yau 4-folds, which is a way to count instantons and coherent sheaves on CY4.
