About Me
I am a Pre-Tenure Associate Professor in the School of Statistics, East China Normal University, where I have worked since November 2025. I received my Ph.D. in Computer Science from Shanghai Jiao Tong University in June 2025 through a joint program with Tsinghua University, advised by Yuchen Guo and Qionghai Dai. Previously, I received my M.Sc. in Computer Science from Fudan University and my B.Eng. in Software Engineering from Northeastern University.
My research focuses on computer vision, deep learning, and efficient AI models. I work on object detection in gigapixel and high-resolution wide (HRW) images, vision Transformers, dynamic sparse computation, and model efficiency. My recent work explores adaptive sparsity, activation-based window pruning, elastic computation, and mixture-of-experts architectures to improve visual perception while reducing computational cost.
I teach Computer Vision and Deep Learning at ECNU. In teaching, I connect the foundations of artificial intelligence with current research and practical projects to help students develop independent thinking and hands-on research skills.
I welcome research discussions and collaborations. Please contact me at wxli@sfs.ecnu.edu.cn.
