I am an assistant professor at the Institute of Software, Chinese Academy of Sciences (中国科学院软件研究所).

Research

I am broadly interested in designing secure and high-performance computer systems, including operating systems, distributed systems, and network systems. Recently, I have been focusing on operating-system support for heterogeneous multi-processor architectures.

Biography

I received my Ph.D. in Computer Science from The University of Hong Kong, advised by Prof. Heming Cui, where I created secure and high-performance distributed systems such as in-datacenter permissioned blockchains.

Before that, I received my master’s degree from Tsinghua University, where I worked with Prof. Kueiming Lo on formal modeling and analysis of network protocols. I received my bachelor’s degree from Beijing Institute of Technology.
