[email protected]; [email protected]

I am an Associate Research Fellow at the School of Software, Shandong University. From May 2023 to July 2024, I am a postdoctoral fellow at the Department of Computer Science, The University of Hong Kong. I received my B.Sc. degree in Computer Science and Technology from the College of Information Science and Engineering, University of Jinan, in 2017, and my Ph.D. from the School of Software, Shandong University, Jinan, China, in 2022. My current research interests include machine learning, image processing, and geometric analysis.
