About Me

I am a fifth-year Ph.D candidate at University of Chinese Academy of Sciences(UCAS), my advisor is Prof. Wei Zou, my co-advisor is Xiaorui Gong. I was a Research Scientist at Pennsylvania State University, under supervision of Dr. Xinyu Xing. I received Bachelor degree from Department of Information Security, University of Science and Technology of China(USTC) in 2014.

My research direction is system security, including vulnerability exploitability, program analysis for exploitability evaluation, exploit generation for OS kernels and knowledge driven approaches for vulnerability analysis.

I started participating various CTF competitions since 2015. I enjoy constructing weird machines and programming with them. here is my blog about CTF games and research experience. I am a co-founder of CTF team Never Stop Exploiting (NeSE). I help organize and craft challenges for X-NUCA(全国高校网安联赛) since 2016.
