Hello! I'm Lily Ge; I also publish and collaborate under my given name, Yijun Ge. I'm a Software Engineering student at the University of Waterloo. My interests lie in Natural Language Processing (NLP), Information Retrieval (IR), Agentic Systems, and Robots. I am fortunate to be advised by Professor Jimmy Lin.
