Junyi Jessy Li

I am an Assistant Professor in the Linguistics Department at The University of Texas at Austin. My research interests are in computational linguistics and natural language processing, especially discourse and pragmatics, and NLP in social contexts.

I obtained my Ph.D. from the Department of Computer and Information Science at the University of Pennsylvania in 2017, advised by Prof. Ani Nenkova. I received my BSE in Computer Science from the University of Michigan and BE in Electrical and Computer Engineering from the UM-SJTU Joint Institute at Shanghai Jiao Tong University. Usually I go by Jessy.
