I am a fourth-year Ph.D. student in the School of Electronic Science and Engineering, Nanjing University, under the supervision of Prof. Qiong Chang and Prof. Yun Li. I was admitted directly to the Ph.D. program after receiving my B.Eng. degree from Nanchang University via a merit-based recommendation and exemption from the national graduate entrance exam.
My research focuses on high-performance parallel algorithm design on GPUs, aiming to accelerate core computational tasks in computer vision, graph analytics, and large-scale data processing. Specifically, I target desktop, server, and embedded GPUs to design algorithms that are highly parallel, computationally efficient, and resource-aware, by considering both algorithmic structure and GPU architectural characteristics.
