About Me
I am a second-year master’s student at Tsinghua University, advised by Prof. Xiu Li. I also conduct research with Vision and Image Processing (VIP) Laboratory, Duke University, advised by Prof. Sina Farsiu. Before that, I received my B.Eng. degree in Software Engineering from Southwest University in 2024, where I graduated with the “Special Scholarship” and was named an “Outstanding Student Representative.” My research interests revolve around the intersection of vision restoration and perception, visual understanding, and multi-agent system.
I am currently seeking PhD positions for Fall 2027 and open to all forms of collaboration.
