I am currently a Ph.D. candidate in Computer Application Technology at the College of Computer Science and Artificial Intelligence, Fudan University, advised by Prof. Cheng Jin. I also work closely with Prof. Weizhong Zhang. I received my B.S. degree in Computer Science and Technology from Fudan University in 2021.

Research Interests

My research interests include but are not limited to:

• Data Efficiency: Data selection, core-set construction, and optimizing the data foundation for model training.
• Model Efficiency: Model compression, efficient training and inference strategies, and acceleration algorithms for diffusion models.
• Model Robustness: Anomaly detection and Out-of-Distribution (OOD) detection to enhance model reliability.
