I am an Assistant Professor at School of Mathematics and Statistics, Beijing Institute of Technology. My office is at 901C, Liberal Arts Building II.

I was a Postdoctoral Fellow at Department of Mathematics, University of Toronto with my mentors Yael Karshon and Marco Gualtieri after being a Visiting Assistant Professor at Cornell University with my mentor Reyer Sjamaar. I received my PhD in mathematics at University of California San Diego supervised by Álvaro Pelayo in 2018 and a BS in mathematics from Tsinghua University in 2014.
