Weiwei Chen

I am an associate professor at the Institute of Logic and Cognition and Department of Philosophy, Sun Yat-sen University, China.

My research navigates the intersection of argumentation theory, logic, and social choice. It is inherently interdisciplinary, spanning philosophy, logic, and artificial intelligence. My work is dedicated to exploring collective decision-making processes, with a particular focus on:

Formal Argumentation: Investigating the structure and dynamics of arguments and debates, and how they influence collective outcomes.
Social Choice Theory: Analyzing methods for aggregating individual argumentative preferences, judgments, or votes into a collective decision.
Interdisciplinary Applications: Bridging the gap between theoretical insights and practical applications in AI, particularly in the realm of collective decision-making.

我是中山大学哲学系、逻辑与认知研究所副教授陈伟伟。我专注于形式论证（formal argumentation）和社会选择理论（social choice theory）。研究位于论证学、逻辑学、政治经济学与AI的交汇处，着重探讨群体决策问题。
