Our group researches computer vision, data structures, and machine learning. We focus on foundational technologies for large-scale and high-performance AI systems, including vector databases, approximate nearest neighbor search, retrieval-augmented generation (RAG), and learned data structures. We are open to motivated students eager to challenge themselves with exciting new topics.
