About Me

I am an assistant professor, Ph.D. advisor at the School of Artificial Intelligence, Shanghai Jiao Tong University. I obtained my Ph.D. at the Department of Electronic and Computer Engineering, National University of Singapore in June 2025, supervised by Prof. Xinchao Wang. Before that, I received my bachelor’s degree in the Department of Computer Science and Technology from Nanjing University in 2021. I was also fortunate to work as a research intern at Rutgers University under the supervision of Prof. Hao Wang and at Baidu Inc. under the supervision of Tianwei Lin.

My research interests include visual synthesis and training with synthetic data. Since 2020, I have published over 10 first-author research papers at top journals/conferences on these topics. Multiple works are selected as paper award nominations, oral, highlight, and spotlight. During my doctoral studies, I received the NUS Research Scholarship and the 2023 National Award for Outstanding Self-financed Chinese Students Abroad.

Currently, I am creating Learning and Synthesis Hub and recruiting Ph.D. students (2~3 every year starting from fall 2026), Master students (1~2 every year starting from fall 2026), and multiple research interns. If you are interested in working with me at Shanghai Jiao Tong University on the following topics:

1. Model Editing for Novel Functionalities, Efficiency, Generalizability, and Safety;
2. Training with Synthetic Data;
3. Visual Generative Model;
4. Applications of the above topics to broader domains, e.g., art, science, robotics, multimedia, etc.,

feel free to reach out via liusonghua{AT}sjtu.edu.cn / liusonghua_site{AT}163.com. We are always looking for self-motivated students actively.

Currently, I have run out of Ph.D. positions for 2026.
