I am a postdoctoral researcher in the Department of Engineering Science at the University of Oxford and a Junior Research Fellow at
Kellogg College.
I obtained my Ph.D. degree (with honors) in 2023 and my B.Eng. degree in 2018, both from the Department of Electronic Engineering at Tsinghua University.
My research interests span data mining, knowledge graphs, foundation models, multimodal learning and trustworthy AI, with applications in healthcare,
biomedicine, urban computing and sustainable development.
