Greetings! I’m a Ph.D. student at Siebel School of Computing and Data Science in University of Illinois Urbana-Champaign, advised by Prof. Fan Lai.

I received my Bachelor’s degree in Computer Science from Georgia Institute of Technology, where I am very fortunate to work with Prof. Tuo Zhao. I am also very fortunate to spend a wonderful summer with Dr. Yu Gan and Prof. Fan Lai as a student researcher in Systems Research@Google in summer 2024, and with Dr. Moyan Li and Dr. Shaoyuan Xu as an applied scientist intern in Amazon in summer 2025.

My research interests lie in building efficient systems for supporting large language models, multi-agent systems, and GenAI. Our work has been trialed in real-world deployments.
