Yuchen Guo

Bio

I am currently pursuing the Master of Science in Artificial Intelligence at Northwestern University, Evanston, Illinois, United States, and I received my Bachelor of Science in Computer Science and Technology with first class honours from Hong Kong Baptist University, Zhuhai, China.

Previously, I worked as research intern at XPixel Group, Multimedia Laboratory (MMLab), Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences (SIAT, CAS), advised by Prof. Chao Dong. And I also conducted research at the Institute for AI Industry Research (AIR), Tsinghua University, advised by Prof. Yilun Chen.

Additionally, I was a Summer Visiting Student in Artificial Intelligence and Machine Learning at the University of Oxford, advised by Prof. Tom Rainforth.

I also work closely with Dr. Shihao Zou at SIAT and Dr. Wei Ji at Yale.
