(Bill) Yuchen Lin

I am a Ph.D. student in Computer Science at the University of Southern California, working with Prof. Xiang Ren who leads the Intelligence and Knowledge Discovery (INK) Research Lab. Previously, I got my bachelor's degree at the IEEE Honor Class in Shanghai Jiao Tong University, supervised by Prof. Kenny Q. Zhu.

I am generally interested in building neuro-symbolic systems that demonstrate a deep understanding of the world, integrating technologies for information extraction, knowledge graphs, machine reasoning, graph neural networks and model robustness. My recent research aims to advance natural language processing (understanding & generation) with commonsense reasoning.
