I am a fourth-year PhD student at Northwestern University. I am fortunate to be advised by Dr. Xinyu Xing. My Research focuses on OS exploitation and defense. I love hacking in the real world. I have done many Linux kernel exploitation and contributed many security fixes to Linux kernel. I used to play CTF a lot with team Nu1L.
