Ao Li (李骜)

I am currently a Lecturer at the College of Computer and Information Science, Chongqing Normal University (CQNU). My research focuses on low-level vision and efficient vision models, with a particular emphasis on image super-resolution. I am also interested in exploring how generative models and large multimodal models can contribute to this area.

Before joining CQNU, I received my Ph.D. degree from the University of Electronic Science and Technology of China (UESTC) in 2026, where I was jointly supervised by Prof. Le Zhang and Prof. Ce Zhu. I received my M.Eng. degree from Chongqing University of Posts and Telecommunications in 2020 and my B.Eng. degree from Chongqing University in 2017. Prior to my doctoral studies, I worked as a researcher at Sinovatio in 2021 and as a research assistant at UESTC in 2022.
