I’m a Second-year Ph.D. student in the School of Computer Science and Technology at Harbin Institute of Technology, Shenzhen, advised by Prof. Cuiyun Gao. I got my Master degree from Harbin Institute of Technology, Shenzhen in March 2023, under the supervision of Prof. Cuiyun Gao. Before that, I received my Bachelor’s degree from Harbin Institute of Technology in June 2020.

I am always open for possible collaborations, and visiting opportunities, please do not hesitate to contact me if you are interested!

Interests

My research interests mainly focus on AI + Software Engineering, particularly Large Language Models (LLMs), Source code understanding, Recommendation
