About Me

I am currently a first-year Ph.D. student at the Department of Computer Science, City University of Hong Kong, under the guidance of Prof. Zhenjiang Li. Prior to this, I did a research internship at HKUSTgz supervised by Prof. Jia Yan. I received the B.E. degree in Software Engineering, from Northwestern Polytechnical University, China, in 2024.

My research focuses primarily on On-device Machine Learning Systems, including:

• System management for on-device LLM inference (e.g., memory, operating frequency, etc.).
• Hardware-software co-optimization for on-device LLM inference (e.g., unified memory and mobile NPU).
• Optimization in wireless communications and networking.
