I am a Ph.D. candidate in the School of Integrated Circuits at Peking University, affiliated with the Institute for Artificial Intelligence, and advised by Prof. Bonan Yan. My research focuses on communication–computation co-optimization and hardware–software co-design for large-scale agent (LLM/RL Agent) systems. Targeting the training and deployment bottlenecks of large-scale agent systems, my work spans workload modeling, communication–computation co-optimization, and heterogeneous computing prototyping, aiming to improve the training, inference, and interaction efficiency of LLM/RL Agent systems across heterogeneous platforms such as AI accelerators, FPGAs, and multi-XPU clusters.
