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 main research interests are in the fields of computer vision and medical image analysis, in particular trustworthy AI tasks including abnormality and rarity learning tasks, OoD detection, fairness learning, federated learning and their applications in medicine. I also have interests in developing multi-modal medical foundational models recently.
