About me

Hi! I’m Yingzi Gao (高英梓), an Assistant Professor at the School of Computer Science and Technology, Shandong University.

I obtained my Ph.D. from the Institute of Software, Chinese Academy of Sciences (UCAS), where I focused on the security of distributed systems.

My research interests include:

  • Byzantine fault-tolerant consensus protocols
  • Distributed key generation and reconfiguration
  • Threshold cryptography
  • Blockchain systems security

欢迎各位同学关注我的研究方向！如果你对区块链共识、分布式系统安全、门限密码系统等领域感兴趣，欢迎随时联系我！我们一起探索更多有趣的课题，共同成长与进步！
