About Me

My name is Sangah Lee 이상아[李尙娥], an assistant professor in the Department of Linguistics at Seoul National University. I am a computational linguist interested in reasoning abilities of LLMs, linguistic probing of LLMs, and multilingual/low-resource scenarios of language modeling. I’m involved in the Computational Linguistics Lab of Dept. of Linguistics, SNU.
