I am Yuanming Ren, a third-year Ph.D. candidate at The Chinese University of Hong Kong, supervised by Prof. Patrick P.C. Lee. My research centers on storage systems, including distributed key-value stores, vector storage, and AI infra. I welcome collaboration opportunities with researchers from diverse backgrounds to tackle exciting challenges in these areas. Please feel free to reach out via renyuanming1@gmail.com.
