About Me

Hello, I am Zhisheng Hu [ 胡智胜 ], a third-year Ph.D. candidate in Department of Computer Science and Engineering at The Chinese University of Hong Kong (CUHK), advised by Prof. Ming-Chang Yang. Before joining CUHK, I earned my B.Eng. from Harbin Institute of Technology, Shenzhen (HITSZ), advised by Prof. Wen Xia in 2022.

My research focuses on building efficient, scalable, and reliable systems for the next generation of hardware and workloads. Specifically, I am interested in:

• Distributed & Storage Systems: Designing efficient storage engines and memory fabrics.
• Emerging Hardware: Optimizing systems for NVMe/NOR Flash, RDMA, and CXL.
• AI Infrastructure: Enhancing ML system performance through architectural innovations.
