Personal information

Currently I’m an associate professor at School of Mathematics and Statistics, Center China Normal University. I received my PhD from the [Max-Planck Institute for Mathematics](https://www.mis.mpg.de/. My advisor was Jürgen Jost and Peter F. Stadler. My dissertation defense was on October 18th, 2014.

I completed my BS in mathematics at Shanghai Jiao Tong University.

My ORCID: https://orcid.org/0000-0001-5934-1326

Research Interests

My research interests are in graph theory and phylogenetic combinatorics, including combinatorics in the application of biology and quantum information.

Here is my dissertation.
