Multimodal Foundation Models · Agentic AI · Video Understanding

About Me

I am a master’s student in Computer Science and Technology at Beijing Normal University (GPA: 4.0/4.0, Rank: 1/71). My research focuses on multimodal foundation models, agentic systems, and structured video understanding. I enjoy turning concrete scientific or product bottlenecks into scalable data, modeling, and post-training pipelines.
