Here is my Curriculum Vitae.

I'm an associate professor in Beijing University of Posts and Telecommunications (BUPT). I received my doctoral and bachelor degrees from Peking University in 2020 and 2015, co-advised by Prof. Gang Huang and Prof. Xuanzhe Liu.

I always look for highly self-motivated undergraduates and graduates. Please directly send your CV to me if you find my research interesting.


I work on systems software, with focus on resource-constrained platforms like edge clouds, smartphones, IoTs, and satellites.


Our team is passionate about building open-sourced systems that can benefit others.

  • mllm - a fast and lightweight multimodal LLM inference engine for mobile devices.

  • RROS - a dual-kernel, Rust-based OS for satellites or other scenarios that need both real-time and general-purpose abilities. RROS = RTOS (Rust) + Linux (C). RROS has been sent into space already!

  • LlamaTouch - Mobile Agents, testbed, and datasets.

  • E2E Federated Learning - an end-to-end federated learning prototype across smartphones.

  • FedAdapter - a parameter-efficient federated learning framework.

  • Mandheling - an on-device training engine with Qualcomm Hexagon DSP.

  • Hotpot - a cute dog feeding project that lasts decades.
