Howdy! I am an Applied Scientist at Amazon Web Services (AWS), where I work on Guardrails for large language model (LLM) safety and, with the GraphStorm team, on a large-scale graph machine learning (GML) framework. I received my Ph.D. from the Department of Computer Science & Engineering at Texas A&M University in December 2025, advised by Prof. Shuiwang Ji in the Data Integration, Visualization, and Exploration (DIVE) Laboratory. Before that, I obtained my bachelor’s degree from the School of Information Science and Technology, University of Science and Technology of China (USTC) in 2020.
My research focuses on (1) LLM safety, (2) trustworthy AI, (3) graph neural networks, and (4) AI for science. My work on GNN explainability, including a taxonomic survey and SubgraphX, has received over 2,000 citations. I also co-developed DIG (2k+ GitHub stars), a library for graph deep learning research, and AIRS (700+ GitHub stars), a collection of algorithms and benchmarks for AI for science.
