About Me

I am an assistant professor at POSTECH GSAI/CSE, leading Language & Intelligence Lab (LIL) under POSTECH NLP Group. Before joining POSTECH, I was an assistant professor at UNIST AIGS/CSE. I earned my PhD from UNC Chapel Hill, where I was advised by Prof. Mohit Bansal. I also worked with Prof. Henry Fuchs on AR applications.
