I am an associate professor at the Nanjing University of Aeronautics and Astronautics. Previously, I worked at ByteDance and Tencent Jarvis Lab (2021-2023). I received my PhD degree in CS from the Hong Kong University of Science and Technology in 2021 under the advising of Prof. Yangqiu Song. I obtained my Master's degree from Zhejiang University, and Bachelor's degree from Harbin Institute of Technology.
My research focuses on LLMs, RAG, Agents.
