About Me

I am an incoming MPhil student at the Hong Kong University of Science and Technology (Guangzhou), supervised by Prof. Mingming Fan. I received my Bachelor of Engineering in Software Engineering from South China Normal University (joint programme with the University of Aberdeen, First Class Honours Expected).

My research interests lie at the intersection of Human-Computer Interaction, Human-AI Collaboration, and Educational AI. I am particularly interested in designing intelligent systems that support group ideation, collaborative learning, and cognitively-grounded assessment.

CHI 2026 CCF-A

Toggle Abstract

In group ideation, whether participants should ideate collaboratively or individually remains controversial. GraftMind enables users to ideate in private workspaces while an AI mediator proactively leverages collective ideas to provide real-time ideation assistance.
