I am a Ph.D. candidate in the School of Computer Science at Northwestern Polytechnical University (NWPU), supervised by Prof. Bin Guo (NWPU) and Academician Yunhao Liu (Tsinghua University, THU), starting from Fall 2021. Before that, I received my B.Eng. in Computer Science and Technology from NWPU (2021) as an Outstanding Graduate.
My research spans Mobile Computing and Resource-Constrained AI (context-aware deep learning on resource-constrained devices, memory-efficient training, cloud–edge collaborative inference and adaptation) and Multimodal Large Language Models (streaming video understanding, hallucination reduction, and anomaly detection).
