I am an Assistant Professor in the Computer Science and Engineering Department of Mississippi State University. Before joining MS State in 2020, I have been working as a research assistant at Virginia Tech. I received an outstanding contribution award from Toyota Research North America in 2016. Currently, I am focusing on graph machine learning and its applications on spatial problems, circuit, molecule, etc.

[Paper]12/2019: Unsupervised learning for material discovery is published in Nature Communications.
Today’s deep learning is still a black box. Similarly, graph neural network is another black box. This incurs difficult in comparison and improvement since each method is acclaimed as state-of-the-art. A unified framework is needed to avoid the potential risks, which is our goal.
Graph neural networks (GNNs) motivate many applications based on network data such as transportation road. However, as a practical scenario, the road has very different characteristics from a smooth network (e.g., social network) often used by GNN experiments. We plan to identify these special features and accordingly adjust GNN to adopt transportation problems.

Material development heavily relies on domain knowledge and professional’s intuitive, which hinders the discovery of new material. We are collaborating with material experts and propose generative models for boosting material discovery.
