Yiyang Su

I am a Ph.D. student in Computer Vision Lab (CVLab) at Michigan State University advised by Dr. Xiaoming Liu. My research is mostly focused on open-set recognition and video understanding. In summer 2025, I worked as an Applied Scientist Intern at AWS AI Labs with Drs. Xiang Xu, Zheng Zhang, Chang Liu, Zhuowen Tu, Anil Jain, and Jon Wu. Prior to joining MSU, I received my Bachelor of Science degrees from the University of Rochester, where I also had the opportunity to work with Dr. Chenliang Xu and Dr. Yapeng Tian on audio-visual sound separation.
