Junyi Jessy Li

I am an Associate Professor in the Linguistics Department at The University of Texas at Austin where I work on computational linguistics and natural language processing. More specifically, my research focuses on discourse processing, language generation, and NLP in social contexts. I belong to the Computational Linguistics Group at UT Linguistics, and the UT NLP Group. I obtained my Ph.D. from the Department of Computer and Information Science at the University of Pennsylvania in 2017, advised by Ani Nenkova. Usually, I go by Jessy.

I am the AI Lead of the Explorable Universe Research Group in the NSF-Simons AI Institute for Cosmic Origins (CosmicAI). I am also a Graduate Studies Committee member in the Department of Computer Science.

Some of the topics that I am currently researching include:

• Discourse Processing: How do humans and machines make sense of long texts? We investigate discourse-level devices at play, e.g., discourse structure, questions under discussion (discourse comprehension as question generation and question answering), and pragmatics.
  • Selected recent work: EMNLP’24 Outstanding Paper, EMNLP’23, ACL Findings’23
• Natural Language Generation: How can we harness, improve, and evaluate text generation? We study document-grounded tasks like text simplification and summarization, and incorporate discourse models in generation.
  • Selected recent work: ACL’24 InfoLossQA, ACL’24 FactPICO, EMNLP’23
• Language and Society: We seek to understand how people use language to express their intentions and emotions, and how we perceive ourselves in connection to the world impacts our language use, often in subtle ways.
  • Selected recent work: EMNLP Findings’24, COLM’24, EACL’23
• Language and Code: We develop methods rooted in NLP and LLMs to understand, generate, and evaluate software evolution and documentation.
  • Selected recent work: ICSE’25, FSE’23, ICSE’23
