About

  • I am a associate research professor in the Institute for Network Science and Cyberspace of Tsinghua University. I received my bachelor’s degree and doctor’s degree in computer science and technology from Shandong University and Tsinghua University in 2005 and 2010 respectively. After graduation, I worked in the government information security management department and well-known Internet companies and network security companies, mainly engaged in the research of network security architecture design and network security protocol design.

    Since 2017, I have returned to the Institute for Network Science and Cyberspace of Tsinghua University to engage in research work related to network security. I have more than 10 years of network security research experience. Some of my research results were deployed by some big IT companies like Alibaba and Huawei. My research interests include protocol vulnerability analysis, Internet infrastructure security measurement, network behavior anomaly detection and Internet underground economy detection etc.
