About Me
I am Tongwei Deng. I received my B.S. degree in 2024 from the School of Computer Science and Technology at Huazhong University of Science and Technology. I am currently pursuing a direct Ph.D. degree at the School of Computer Science, Peking University, and expect to graduate in June 2029.
My research focuses on software engineering, with particular interests in code refactoring, software maintenance, and model post-training.
Please feel free to email me if you are interested in my research or simply want to talk!
