Hello! I'm Lily Ge; I also publish and collaborate under my given name, Yijun Ge. I'm an undergraduate Software Engineering student at the University of Waterloo. My interests lie in Natural Language Processing, Information Retrieval, Agentic Systems, and Robots. I am fortunate to be advised by Professor Jimmy Lin.
Experiences
Research Assistant
I contribute to IR research infrastructure through Anserini, Pyserini, and RankLLM, and led QuackIR and rosaOS.
AI Engineer
I built RAG pipelines, enabled citation extraction across various model providers, and prepared data for annotation.

Projects
An AI-driven visual novel with LLM dialogue, RAG-backed long-term memory, local stable diffusion, and custom game logic through a Flask backend.
Webcam-based keyboard input from ASL hand gestures and MediaPipe gesture shortcuts for control keys, with modular AI components and real-time OpenCV video.
