Yuxi Hu, 23, is a postgraduate student at Fudan University, affiliated with Research Institute of Intelligent Complex Systems. And she hold a bachelor’s degree in Mathematics and Applied Mathematics from Tongji University. Her research focuses on modeling complex networks for public health vaccine decision-making, where she integrate large language models to analyze public sentiment on social media and employ agent-based modeling to simulate population behavior and decision dynamics. She has received multiple scholarships and academic honors for her rigorous and collaborative approach. Noting that the course theme aligns closely with her work—particularly in dynamically monitoring vaccine hesitancy and addressing trust crises—she is looking forward to deepening my methodological expertise, collaborating with peers from diverse backgrounds, and contributing perspectives and thoughts from mainland China.
