Hi, I'm
Yiren Liu
PhD Candidate in Informatics, UIUC
I'm a doctoral student at the University of Illinois Urbana-Champaign , advised by Prof. Yun Huang and Prof. Tal August. My research interests include human-AI collaboration in the context of scientific research and ideation. My recent publications discussed the design and evaluation of novel systems for research ideation with LLM-powered agents.
