I am a Master of Science in Computer Science (MSCS) student at the University of Illinois at Urbana-Champaign, working with Minjia Zhang. I am very interested in large-scale vector databases on GPUs, efficient data management systems, and high-performance computing for AI applications.

Feel free to reach out via email if you are interested in my research.
