Tianfang Han's research focuses on both basic and applied (human factors) aspects of cognitive psychology. In basic research, Han investigates the mechanisms underlying alertness (or temporal preparation), which is regarded as a basic component of human attention system. He is also interested in how conflicting information affects task performance and interacts with preparation processes. In the area of human factors, Han studies the driving behaviors and mutual vehicle interactions in roundabouts and other risk-related scenarios using his experience and knowledge from basic research.
