Chao Shang

I am an Applied Scientist at Amazon AWS AI. My research interests lie primarily in deep graph learning, natural language processing and machine learning using large-scale graph-structured and text datasets, with an emphasis on Large Language Models (LLMs), knowledge graphs, question answering, and drug discovery. I received my Ph.D. from the Computer Science and Engineering Department, University of Connecticut, advised by Prof. Jinbo Bi. I got my M.S. degree at Beijing University of Posts and Telecommunications (BUPT).
