             Graph neural networks (GNNs) generalize the existing deep learning techniques to graph structured data including biological networks, molecular graphs, academic networks, and knowledge graphs. In this project, we aim to improve the existing GNNs to be more expressive and sample-efficient. We are particularly interested in directions like architecture design, data augmentation, and self-supervised learning.
