About me

I am currently a Ph.D student at Sun Yat-sen University, where I am supervised by Prof. Zibin Zheng and Dr. Jiachi Chen. I also play Smart Contract CTF and bug hunting competitions (e.g., Code4rena) for fun.

My research interests include:

• Security of Blockchain and Smart Contract

• Fuzzing
