About Me

I received my bachelor's degree in the Department of Electronic Engineering and Information Science at the University of Science and Technology of China (USTC), Hefei, China, in 2022, as a member of the Talent Program in Artificial Intelligence.
I am currently a Ph.D. candidate in Control Science and Engineering at Department of Automation, USTC, under the supervision of Prof. Tianzhu Zhang.
My research interests lie in computer vision and machine learning, with a particular focus on semantic segmentation, unsupervised domain adaptation, and semi-supervised learning.
