About SIGCoLED
SIGCoLED is an interdisciplinary research group focused on the frontier of Human-AI and Multi-agent Collaboration. We bring together researchers and practitioners from various domains such as computer and information science, education, psychology, and human-computer interaction, to explore how humans and intelligent systems (not limited to LLMs) can effectively and efficiently learn from each other, and discover together.
We are committed to open science principles, with the aim of enhancing human potential (both kids and adults) and improving the accessibility, reliability, and explainability of human-centered AI. Our research topics focus on real-world challenges in education, scientific discovery, creative work, and professional knowledge domains where human-AI collaboration can unlock new possibilities.
Research Areas
Learning
Developing intelligent systems that can both learn from and teach humans, creating interactive environments to support knowledge acquisition.
Exploration
Investigating how artificial intelligence expands human's capabilities and skills for new knowledge, or identifying novel directions and opportunities.
Discovery
Combining computational pattern recognition with human's intuition to uncover insights in complex data, through synergistic human & AI collaboration.
