Since September 2022, I have been an assistant professor (tenure-track) at the Department of Information and Computational Sciences, School of Mathematics and Statistics, Wuhan University (my Alma Mater). My office is Xi-Bei Lou 209.

From November 2020 to August 2022, I was a designated assistant professor (tokunin-jokyo, 特任助教) at Graduate School of Mathematics, Nagoya university. I was part of the QLEAP theory group lead by Professor François Le Gall.

From June 2018 to June 2020, I was a Postdoctoral researcher at Centrum Wiskunde & Informatica (CWI), the national research institute for mathematics and computer science in the Netherlands, supervised by Prof. Ronald de Wolf and Dr. Michael Walter. I was also affiliated with the Research Center for Quantum Software (QuSoft).

I received my Ph.D. from Centre for Quantum Software and Information (QSI), University of Technology Sydney (UTS), supervised by Prof. Runyao Duan and Dr. Youming Qiao (and informally co-advised by Prof. Andreas Winter). Before that, I received my B.Sc. (with Hongyi honor) in 2014 from School of Mathematics and Statistics, Wuhan University.

I am the organizer of the QLEAP theory seminar. In 2020, I co-organized an online reading group “From Euclidean to Geodesic Convex Optimization”.

- Classical and quantum zero-error information theory
- Classical and quantum algorithms (e.g. for group actions and for linear algebraic problems)
- Noncommutative generalizations of the graph theory
