I am an undergraduate researcher at Hubei University’s Manchester Metropolitan Joint Institute and an incoming M.Eng. student in Communication Engineering at East China Normal University’s School of Excellent Engineers, starting in September 2027. I am currently a research intern in Prof. Lin Yang’s group at The Hong Kong Polytechnic University and an Algorithm Research Intern at Kingsoft AI Product Center.

My research focuses on reliable learning and decision-making, spanning foundation models, reinforcement-learning agents, multimodal perception, and safety-critical control. At PolyU, I develop algorithms for medical AI, including large language models for nursing and diabetes care, together with evaluation frameworks for these models. At Kingsoft, I work on foundation-model pretraining and game-playing agents.

I develop DanKS, an open-source GuanDan AI system, and awesome-latex-skills, a collection of academic workflows for AI agents. I am also a Kaggle Competitions Expert, ranked in the top 1%. Previously, I interned at Z.ai and TeleAI.
