Siyu Xu is a Ph.D. student at The University of Sydney, supervised by A/Prof. Chang Xu. His research focuses on Embodied AI, specifically Vision-Language-Action (VLA) models and World-Action (WAM) models. His goal is to develop efficient and general-purpose robotic systems capable of understanding and interacting with the world through vision, language, and actions, enabling them to seamlessly assist humans in various real-world tasks and everyday life.
Recently, he has been particularly interested in improving the out-of-distribution (OOD) generalization and efficiency of VLA/WAM systems, with the goal of making embodied foundation models more reliable and practical for real-world deployment.
