Yu Tian

Yu Tian is a postdoctoral researcher at the University of Pennsylvania. Prior to joining UPenn, he was a postdoctoral research fellow at Harvard University. He earned both his Ph.D. and his BSc with First Class Honours in computer science from the Australian Institute for Machine Learning (AIML) at the University of Adelaide.


Research

My primary research interests lie in computer vision and medical image analysis, focusing on trustworthy AI tasks such as abnormality and rarity learning, out-of-distribution detection, fairness learning, interpretability, and federated learning, with an emphasis on their biomedical applications. Recently, I’ve also been exploring the development of multi-modal medical foundation models and studying their trustworthiness.
