Chiyuan Wang — PhD Student, Peking University

About

I am a Ph.D. student in the School of Computer Science at Peking University, affiliated with the Center on Frontiers of Computing Studies (CFCS). I work on multi-agent systems, quantitative macro, and AI tools for social science.

I am currently supervised by Prof. Xiaotie Deng and co-advised by Prof. Bo Li and Prof. Yaodong Yang.

I have been interning at the Beijing Institute for General Artificial Intelligence (BIGAI) since 2025.

I received my B.S. in Data Science from Yuanpei College at Peking University (2021–2025).
