Work experience

• Research Scientist, Sei Labs, Inc., Jun 2026 – present
  • Leading the Gas Repricing Project for the Sei blockchain to align on-chain gas costs with the actual resource consumption of the execution and storage layers.
  • Contributing to a dual-path low-latency consensus project that reduces transaction commit latency by combining a fast optimistic path with a fallback path.
• Research Intern, Mysten Labs, Inc., Jun 2025 – Sep 2025, Remote
  • Worked on a research project on transaction scheduling in Multi-proposer consensus to accelerate parallel transaction execution and mitigate congestion under high-contention workloads.
• Fullstack Software Engineer Intern, Hangzhou Zhuxing Information Technology Co., Ltd., Jul 2020 – Oct 2020, Hangzhou, China
  • Developed a WeChat mini-program that enables the fourth official at football matches to record real-time match data.

Open-source
