My name is Liyan Tang (唐立言 in Chinese). I’m a third-year Ph.D. student in the AI Health lab and TAUR Lab (Text Analysis, Understanding, and Reasoning) at UT Austin. I have been working with Ying Ding, Greg Durrett, Yifan Peng and Justin F. Rousseau (alphabetical order). My research focuses on text generation and evaluation, as well as their applications in the clinical domain.
