I am a Ph.D. student in Computer Science and Technology at Southeast University, advised by Prof. Lei Feng. Previously, I received masterโs degrees from Southeast University and Monash University through a double-degree program, with Prof. Guilin Qi as my advisor. I received my bachelorโs degree in Computer Science and Technology from Hefei University of Technology in June 2021.
My research interests include:
- Fine-tuning and reinforcement learning for LLMs
- LLM-based autonomous agent architectures
- Multi-agent collaboration
