Hi, I’m currently a fourth-year PhD Student in the College of Computer Science and Technology at Zhejiang University (ZJU), and expected to get the PhD degree in 2027. I’m co-advised by Prof. Wei Dong (董玮) and Prof. Yi Gao (高艺). I work closely with Prof. Borui Li (李博睿) and Prof. Jiamei Lv (吕嘉美). Prior to that, I received my B.E. degree from the School of Electronics and Information Engineering in Hangzhou Dianzi University (HDU), Hangzhou, 2022, advised by Prof. Long Chen (陈龙).

I work on systems and security for AIoT, with a focus on system software for confidential computing in IoT.

Research Overview:

I’m currently working on the following directions:

• Generative safe OS with confidential computing support for IoT — Toward automatically constructing a secure-by-default OS and toolchain for TEE-enabled IoT devices.
  • LLM-assisted secure application development: frameworks that help developers build TEE-based secure IoT applications correctly.
    • IPSN’24, dTEE
• Real-time, cloud–edge–end collaborative confidential AI inference — Key techniques for low-latency and privacy-preserving inference on IoT devices with TEE support.
  • CCS’25, TensorShield

I used to work on (and still build upon) the following topics:

• Delta compression / differencing algorithms for software updates
  • Container Deduplication: ATC’24, SimEnc, TOS’25, SimEnc+
  • Mobile APP updates: TMC’24, sdiff, INFOCOM’24, MDiffPatch
