About me

My CV : link

This is Ziyi Guo, a third year student studying in Sichuan University, Chengdu, China. I plan to apply for a PHD position in the term of 2023 Fall. My general interests lie in System Security, currently focusing on OS Kernel Security and Container Security for several years.

Currently, I am fortunate to be advised by Prof. Qi Li as a Research Intern. And, I also work closely with Yi He@THU-NISL who helps me a lot.

Also, I have rich System Security experiences both in industrial community and academic community, including at

Network and Information Security Lab @ Tsinghua University
- Advised by Prof.Qi Li and co-operating with Yi He ;
Tencent Security Xuanwu Lab
- Mentor: HuiMing Liu, the leader of Mobile Security Research Group in Xuanwu Lab;
ISCAS and Huawei 2012 OS Lab
- Mentor: Lifu Chen, Huawei 2012 Labs Software Research Center, OS Lab;
StarCross Technology

And I have attended many CTF Contests, including DEFCON 29 CTF World Final & Quals as a member of r3kapig. During these contests, I focus on Pwn challenges which help me cultivate my Vulnerabilities Discovery ability and Fuzzing ability.

Lastly, I have great enthusiasm about debuging and figuring out many hard problems, especially for OS Kernel and other low-level Computer System things.
