Since November 2020, I am a designated assistant professor (tokunin-jokyo, 特任助教) at Graduate School of Mathematics, Nagoya university. I am part of the theory group lead by Professor François Le Gall, and supported by MEXT Quantum Leap Flagship Program (MEXT Q-LEAP).

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 honour) in 2014 from School of Mathematics and Statistics, Wuhan University.

- Classical and quantum zero-error information theory
- Classical and quantum algorithms (e.g. for group actions and linear algebra)
- Noncommutative graph theory
