I am a third-year doctoral student in the School of Cyber Science and Technology at Shandong University, advised by Prof. Wenrui Diao. I have received a scholarship from Shandong University, and I am currently a visiting scholar at George Mason University (advised by Asst. Prof. Xiaokuan Zhang). I am interested in the Web3 ecosystem, especially Dapps and crypto wallets.

During my master's studies, I spent significant time learning the basics of blockchain. As a result, I am familiar with the principles of blockchain technology, such as consensus protocols. Also, I proposed a protocol to improve the efficiency of transaction propagation within a blockchain network.

I began my doctoral research approximately two years ago. My first research deeply investigated the security risks caused by centralization in decentralized (Web3) ecosystems. I presented this research at The Web Conference 2023. This research also attracted attention and was featured in Shandong University's campus news and the journal Netinfo Security.

I have extensive programming experience. I have contributed to commercial projects. Several years ago, working as an independent developer, I created two web systems for a company that has more than 50 franchise outlets. To date, these systems are still functioning well. In addition, I am also passionate about open-source projects and have open-sourced some of my work.

In my spare time, I enjoy skateboarding, and I also like music and LEGO.
