Hwanhee (Henry) Lee

I am an Assistant Professor in Department of AI at Chung-Ang University, Seoul, Korea. My Research Interest is in the field of Natural Language Processing, especially about (i) Natural Language Generation and Evaluation, (ii) Factual Consistency Evaluation and Optimization, and (iii) Truthful and Safe Language Models.

I've been working in the Department of Artificial Intelligence at Chung-Ang University from March, 2023 as an Assistant Professor. If you're interested in the lab, please visit this page.
