About Me

I’m Guanyu Li, a 4th-year Ph.D. candidate in Institute for Network Science and Cyberspace of Tsinghua University, advised by Prof. Mingwei Xu and Prof. Jun Bi (late). Before this, I received my B.Eng. Degree in School of Computer Science & Technology from Huazhong University of Science and Technology.

Research Interests

My research works explore how to utilize the programmability of networks and kernels to enhance the security of systems. Hence, I am familiar with Software Defined Networking (SDN), Network Function Virtualization (NFV), and Programmable Data Plane (PDP, P4). In addition, I have digged into a set of fields, such as Cloud Gateway, Denial-of-Service attacks (DoS), Intrusion Detection/Prevention System (IDS/IPS) and etc.
