I'm a Research Scientist at Meta, where I work on elastic capacity management and infrastructure optimization. I received my Ph.D. from Rutgers University, under the guidance of Prof. Dong Deng.

My research interests span similarity search, vector data management, and database systems. During my Ph.D., I focused on developing novel algorithms and practical indexing structures to address complex data challenges.

Prior to my Ph.D., I earned my Master's degree from Rutgers University and my Bachelor's degree from the University of Electronic Science and Technology of China.
