I am currently a PhD candidate in the IMCL Group supervised by Prof. CAO Jiannong with the Department of Computing, The Hong Kong Polytechnic University (PolyU). Before that, I received the B.Eng. degree in Computer Science and Technology from Northeastern University (NEU) in 2020, and M.Sc. degree in Technology Innovation from the University of Washington (UW) in 2022.

I’m broadly interested in blockchain technology in Web 3.0. Currently, I’m focusing on the topics listed below:

📖 Blockchain Oracle

📖 Real-World-Asset (RWA) Verification

📖 Decentralized Finance (DeFi)
