Junchi Yu
I am a Postdoc Researcher at TorrVision Group, University of Oxford, working with Prof. Torr. My research employs a graph-based approach to building trustworthy learning and reasoning systems, using Large Language Models and Graph Neural Networks while exploring their applications in scientific discovery.
I obtained my Ph.D. at the Institute of Automation, Chinese Academy of Sciences, advised by Prof. Ran He. I was a research intern at the AI4Science Team, Shanghai AI Lab, working with Dr. Dongzhan Zhou. I was a research intern at the Machine Learning Center, Tencent AI LAB, working with Dr. Tingyang Xu, Dr. Yu Rong, Dr. Yatao Bian and Prof. Junzhou Huang. I was a visiting student at the Department of Computer Science, Yale University, working with Prof. Rex Ying.
I am awarded the President Award of the Chinese Academy of Sciences (CAS), which is known as the highest award for graduate students in CAS.
