Currently, I am a fourth-year Ph.D. candidate of Websoft Research Group at Department of Computer Science and Technology, Nanjing University. I received my B.Sc. degree from Chongqing University in June 2020. In the same year, I was admitted to study for a Ph.D. degree at Nanjing University under the supervision of Prof. Yuzhong Qu.

I am also interning at Tongyi Laboratory, Alibaba Group starting in July 2024.

Feel free to reach out to me if you’re interested in my research.

Research Interest

My past research focuses on Complex Reasoning over Structural Environments including Knowledge-Based Question Answering(KBQA) and Text2SQL. Currently, I primarily focus on Auto Alignment, Instruct-evol, and Task Specific Agent.
