I am an associate professor at the Morningside Center of Mathematics and the Institute of Mathematics of AMSS, CAS.
I graduated from UC Berkeley under the supervision of Professor Katrin Wehrheim. After that, I spent 3 years as a postdoctoral member at the Institute for Advanced Study working with Professor Helmut Hofer.
I am interested in symplectic topology, more specifically, symplectic field theory and its applications. Here is my CV.
