I am a visiting scholar in the Computer Science department at Purdue University, advised by Prof. Xiangyu Zhang. My research focuses on Web Security, and I am keen on delving into Web3 Security in the future.

Before coming to Purdue, I received my master’s degree at School of Cyber Science and Engineering at Shanghai Jiao Tong University. I was a member of NSSL. Additionally, I participated in CTFs as a member of 0ops and Katzebin.

I am currently looking for a PhD position in 24 Fall.
