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.

Research

I work on the intersection of AI and systems software, with a focus on resource-constrained platforms like robotics, mobile devices, satellites, etc. For now, the long-term, central question that I seek to answer through my research is: "when AGI comes, what kind of system software will be needed".

(✓) I'm now working on following directions.

• Efficient on-device (multimodal) LLM - Human brains also function without clouds, right?

• Physical Intelligence - The recent focus is embodied navigation, envisioning that robots shall move like humans in human space.

• Satellite Computing - Satellites, as the next-generation platform, will carry exciting applications that are unaffordable on the ground.

(✘) I used to working on following topics but not anymore!

• GUI and Computer Use Agents
• Efficient on-device AI in pre-LLM era.
• Federated learning.
• Computing at edge clouds.

Open-sourced Projects

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!
