About me

I am a PhD student supervised by Prof. Xin Wang and Prof. Kun Fang at QuAIR Lab from Information Hub, The Hong Kong University of Science and Technology (Guangzhou). My research interests include quantum information theory and quantum resources.

Previously, I obtained my M.Sc. in Cyber security supervised by Prof. Zhenyu Huang at the University of Chinese Academy of Sciences and my B.Sc. in Mathematics at Applied Mathematics at China Agricultural University.
