About me

I am currently a Ph.D student at Sun Yat-sen University, where I am supervised by Prof. Zibin Zheng and Prof. 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

Experiences

  • Visiting Ph.D student in Nanyang Technological University, from June 2025 to November 2025, working on security of blockchain.

  • Research Intern in Ant Group, from July 2022 to May 2024, working on security of smart contracts.
