I’m Zitong Shi (史梓桐), a PhD student in Computer Science at the National University of Singapore, advised by Prof. Anthony Kum Hoe Tung.
My research focuses on hierarchical reasoning and graph learning. I am particularly interested in formalizing complex problems through structured representations, motivated by the view that many real-world problems can be naturally modeled as hierarchies or graphs.

| Developing methods that decompose complex problems into hierarchical structures to support systematic, interpretable, and generalizable reasoning. | Studying robust, efficient, and federated learning over graph-structured and text-attributed data. |
I explore how hierarchical and graph-based structures can enable more systematic, interpretable, and generalizable approaches to reasoning and learning.
