About Me

I am a final-year Ph.D. student at the Department of Computer Science and Technology of Nanjing University, advised by Xiaoxing Ma and Jian Lü, and a member of the Institute of Computer Software. Before that, I received my B.Sc. degree from the School of Mathematics at Southwest Jiaotong University and my M.Sc. degree from the Software Institute of Nanjing University.

Research Interests

Before the large language model (LLM) era, my research mainly focused on the integration of deep learning and software engineering, particularly in enhancing quality assurance for deep learning models and advancing software engineering automation through deep learning techniques. Additionally, I was deeply engaged in mathematical optimization, including developing fast algorithms and theoretical analysis for minimax and bilevel optimization in large-scale machine learning tasks.

With the emergence of the LLM, my research interests have switched to neuro-symbolic AI. Alongside exploring the theoretical foundations of neuro-symbolic learning, I am especially interested in its practical applications, such as leveraging LLMs for mathematical reasoning, theorem proving, and verified code generation.
