I am a senior software engineer at Moqi since Feb
2017. Before that, I was a researcher at
Huawei Noah's Ark Lab.
I received my PhD degree in Computer Science from the Chinese
University of Hong Kong (CUHK), under the supervision of
Prof. John C.S. Lui.
I was a member of the Advanced Networking and System Research Laboratory
(ANSRLab) at CUHK.
I received my Bachelor degree in Computer Science from Shanghai Jiao Tong
University in 2012, where I was a member of
ACM Class.
