About

Hello! I am Shaokang, a Ph.D. candidate in Computer Science at UC Davis, advised by Prof. Mohammad Sadoghi in the ExpoLab.

My research focuses on scalable Byzantine fault-tolerant (BFT) systems, spanning consensus protocols, blockchain systems, and distributed databases. I am particularly interested in hardware-assisted designs using trusted execution environments (TEEs) and RDMA. I have also recently been exploring how large language models (LLMs) can assist in the design and operation of computer systems.

I serve as a Podling Project Management Committee (PPMC) member for the Apache ResilientDB open-source project and am leading its upcoming v1.13.0 release, scheduled for September 30, 2026.

Prior to joining UC Davis, I received my B.E. in Computer Science from SUSTech in China, where I worked under the supervision of Prof. Yinqian Zhang and Prof. Jianyu Niu in the Teecert Lab.
