About me

Greetings! I am Xinyi Mou.🤡 I am currently pursuing a Ph.D. at Fudan University, where I’m advised by Prof. Zhongyu Wei. I am also a member of the Data Intelligence and Social Computing Lab (Fudan DISC). During my PhD, I’ve spent a precious time with the THUNLP Lab at Tsinghua University, advised by Prof. Zhiyuan Liu, Prof. Huimin Chen and Prof. Chen Qian. I am also very fortunate to have been advised by Prof. Yulan He during my visit to KCLNLP.

Research Interests

My work spans Natural Language Processing and Computational Social Science. I’m particularly excited about these research thrusts:

• 🤖Social Simulation empowered by Large Language Models.
• 💻Explore and Improve the Capabilities of LLMs to Solve Computational Social Science Tasks.
• 👩‍⚖️User Modeling and Discourse Analysis.

News

• 04.2026 I finish my visit to King’s 🏛😢Many thanks to Prof. He and all my collaborators and friends!
• 02.2026 Our social simulation survey has been accepted by ACM Computing Survey!😊
