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) Context Engineering and Memory of Language Models, (ii) Verifiable Safety and Policy Alignment in Language Agents, and (iii) Collaborative Intelligence in Multi-Agent Systems.

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.
