About Me
I began my Ph.D. at the Institute for AI Industry Research (AIR), Tsinghua University in 2022, advised by Prof. Yunxin Liu (刘云新) and working closely with Prof. Ting Cao (曹婷). Before that, I earned my B.E. in Electronic Engineering from Tsinghua University.
My doctoral research focuses on systems optimization for on-device AI inference, with the goal of running frontier models efficiently on resource-constrained devices. Representative work includes FlexNN (MobiCom 2024), Vec-LUT (MobiSys 2026, Best Paper Award Runner-Up), and OxyGen (NeurIPS 2026).
An overview of my doctoral work: MobiSys 2026 Rising Stars Forum
I am currently working on embodied AI, exploring efficient inference and deployment of embodied foundation models (VLAs and WAMs), as well as self-evolving physical intelligence.
