Greetings 👋!

I am a Ph.D. student from the College of AI at Tsinghua University, where I currently work with Prof. Miao Liu.

Previously, I received my B.Eng. degree from the Department of Computer Science and Technology, also at Tsinghua University.

My research interests are primarily in computer vision and multimodal modeling.

During my undergraduate studies, I had the privilege of working with Prof. Shi-Min Hu, Dr. Tai-Jiang Mu, Prof. Sabine Süsstrunk, Prof. Qixing Huang, and Prof. Li Yi.

If you are interested in collaborating on projects, discussing ideas, or simply want to connect for any other reason, please feel free to drop me an email!
