Wai-Tat Fu

Wai-Tat Fu is a professor of Computer Science at the University of Illinois Urbana-Champaign, whose research spans the fields of Human-Computer Interaction and Cognitive Science. He specializes in understanding and optimizing user behaviors through cognitive models, and has proposed influential theories such as the “Soft Constraints Hypothesis” and “SNIF-ACT.” His research examines topics including information seeking, social computing, online credibility judgments, and crowdsourcing, with a focus on how cognitive factors influence decision-making and interaction in the digital world. Professor Fu's work provides valuable theoretical and empirical foundations for designing more effective and human-centered interactive systems.
