I am a senior undergraduate student with a strong interest in Multimodal LLMs, Tool-Using Agents and Spatial Intelligence. My research vision is to develop super-intelligent yet lightweight Multimodal LLMs, enabling machines to perceive, plan, reason, and act through the autonomous integration of multi-sensory signals, external tools, and knowledge, giving rise to superhuman yet controllable intelligence in downstream tasks such as Video Understanding, Embodied Robotics, Autonomous Driving, and Medical Diagnosis.
Research Interests and Highlights
-
Multi-Sensory Perception, Integration and Reasoning: How can machines extract learnable neural-symbolic concepts from the complex physical world to enable grounded understanding, integration, interaction, and decision-making across multi-sensory signals, ultimately leading to superhuman yet interpretable intelligence?
-
World Modeling, Long-Term Video Understanding and Spatial Intelligence: Toward multimodal superintelligence, guiding foundation models to deeply understand the underlying mechanisms of the complex physical world, internalize world dynamics within their parameter space, and reason about complex object properties and interactions in dynamic 3D environments.
-
In-the-wild Environment-Interactive Foundation Agents: How can we teach foundation models to see, plan, and act in open-world settings, while autonomously interacting with external environments such as tools, knowledge bases, and simulators, thereby continuously extending their capability boundaries in real-world applications?
