About

I am a third-year Ph.D. student in the Internet of Things (IoT) Thrust at The Hong Kong University of Science and Technology (Guangzhou), advised by Prof. Huangxun Chen. Before that, I received my B.S. degree in Computer Science and Technology from Harbin Institute of Technology (Shenzhen) in 2024.

My research focuses on:

• Multi-modality memory systems
• Proactive AI assistants
• Device acceleration and optimization in smart environments

I am always happy to discuss research and explore collaborations, so please feel free to reach out. I am also looking for postdoctoral opportunities after graduation.
