👨‍🎓 About Me

I am Yuxuan Su, a Ph.D. student in Computational Social Science at Tsinghua University. I am based in the Department of Social Science, Haidian District, Beijing, China.

My research sits at the intersection of AI alignment, computational social science, and political governance. I study how diverse human preferences, institutional norms, and social choice mechanisms can be incorporated into AI systems, while also examining the methodological role and governance risks of AI in social scientific discovery.

I received my B.A. in History from Tsinghua University in June 2025, with a GPA of 3.99/4.0 and ranking in the top 1%. I am also the Founder & CEO of Beijing Entropy Order Technology Co., Ltd., an AI alignment data provider for LLM developers.

🔬 Research Interests

  • AI Value Alignment: I study how diverse human preferences, social choice mechanisms, and institutional norms can be incorporated into AI alignment, enabling models to navigate value pluralism and conflict rather than optimize for a single preference.

  • AI for Social Science: I explore AI's methodological role in social scientific discovery, with particular attention to improving the reliability and validity of AI tools for long-horizon social simulation tasks.

  • Authoritarian Governance and AI Surveillance: I examine how authoritarian states use AI for social monitoring, opinion manipulation, censorship, and repression, and how technical, institutional, and governance safeguards can reduce risks to human rights and public freedoms.
