Biography

Hello! I am Zhangchi Qiu, a Research Fellow at Griffith University. My research mainly focuses on artificial intelligence and data mining, with particular interests in large language models, knowledge graphs, and recommender systems. I am especially interested in developing knowledge-aware and trustworthy AI systems that support personalised decision-making.

I am a core member of the AI4Health Lab, led by Prof. Alan Wee-Chung Liew, and the TrustAGI Lab, led by Prof. Shirui Pan. Previously, I obtained my PhD in computer science from Griffith University under the supervision of Prof. Alan Wee-Chung Liew, Prof. Shirui Pan, and A/Prof. Hui Tian.
