# About me

I am currently a Staff Researcher at the Institute for Quantum Computing, Baidu Research.

Previously, I was a postdoctoral fellow in Norbert Lütkenhaus’s optical quantum communication theory group, at the Institute for Quantum Computing (IQC), University of Waterloo. Before that, I was a postdoctoral research associate in the Department of Applied Mathematics and Theoretical Physics (DAMTP) at the University of Cambridge, where I worked with Hamza Fawzi. I received my PhD degree in quantum information from the University of Technology Sydney (UTS:QSI) in 2018, under the supervision of Prof. Runyao Duan and Prof. Mingsheng Ying.

My research interests include quantum information theory, quantum resource theory, quantum cryptography and optimization theory.

You can find me on Google Scholar and arXiv. My academic CV is available here.
