Profile Page

Hi! I am a first-year Ph.D. student in the Microelectronics Thrust at The Hong Kong University of Science and Technology (Guangzhou), advised by Dr. Jian Zhang. I received my B.E. degree from the School of Computer Science and Engineering, Sun Yat-sen University in 2024, where I conducted research under the guidance of Associate Professor Xianwei Zhang.

My primary research interests lie in GPU architecture and storage systems, with broad interests in MLSys, compilers, LLM agent applications, and human-computer interaction. My work aims to efficiently run core operating system functionalities on GPUs, thereby accelerating important applications such as large language models.
