To better facilitate human-autonomy teaming (HAT) in the future hybrid society, my research entwines communication, cooperation, and coevolution between humans and artificial intelligence (AI). Specifically, I model trust in human-AI real-time communications, social interactions, and long-term dynamics in safety-critical domains. My research findings further the understanding of trust in HAT and provide broader design implications for conversational robots, safety policy for autonomous vehicles, and theoretical frameworks for safe-critical sociotechnical systems.
