Current Key Projects
🌟 Human-centered AI | Generative AI for X (e.g., Science, Education, Healthcare).
> We conduct interdisciplinary research on how humans and intelligent systems (not limited to LLMs) can effectively and efficiently learn from each other, and explore the world and universe together.
> We are building the Special Interest Group on Human-AI Collaborative Learning, Exploration, and Discovery (InspAIre).

🚀 National Large Language Model Programme (MERaLiON SG)
> Working on improving multilingual and multimodal LLMs' capabilities of knowledge and reasoning.
