Hi! My name is Jiaju Chen, a Master’s student at Rice University. My research interests lie in Human-Centered AI, including Human-Computer Interaction and Natural Language Processing. In particular, I am interested in how to design, develop and evaluate LLM-powered systems that are flexible, adaptive, and personalized. My current work focuses on LLM-powered systems for children’s education. I worked closely with Prof. Yuling Sun during my undergraduate study. More recently, I am a research assistant at the Human-Centered AI Lab at Northeastern University, working on projects advised by Prof. Dakuo Wang.
