I am a PhD student in the School of Mathematical Sciences of Fudan University advised by Prof. Wu Quanshui. My current research interests lie primarily in noncommutative algebra/geometry, Poisson algebra/geometry and quantum group theory. I am also interested in Rubik’s Cube, table tennis and badminton. Here is my homepage on the website of the World Cube Association.
Previously, I received my bachelor’s degree in Mathematics and Applied Mathematics at Shanghai University, supervised by Prof. He Zhuo-Heng.
