Research Interests
My research interests span several fields, including Multimodal Large Language Models, Embodied AI and AI4Science:
Multimodal Large Language Models integrate information from vision, language, and other modalities to perceive, reason, and interact with complex environments, with our research focusing on fine-grained multimodal understanding, cross-modal alignment and reasoning, efficient model reuse, and trustworthy intelligent systems.
Embodied AI explores how intelligent agents learn and adapt through interactions with the physical world, enabling them to perceive, reason, and act in complex environments. Our focus is on enhancing autonomous agents’ perception, reasoning, and multimodal interactions by integrating physical commonsense and environmental feedback, advancing decision-making in dynamic settings.
AI4Science applies artificial intelligence to solve scientific problems, aiming to accelerate discovery, optimize experimental design, and enhance computational efficiency. Our focus includes analyzing and modeling quantum computing, DNA nanostructures, and related topics.
