profile picture Pronounced as [Young] [Hoon]

I am a fifth-year Ph.D. student in Computer Science at Purdue University. My research focuses on Natural Language Processing, Computational Social Science, Representation Learning, and Explainable AI. Specifically, I am interested in discourse analysis within various domains including hate speech, subjective preference, counseling conversations, etc., and systematic approaches to represent discourse more effective and explainable to humans as well as to Large Language Models. I am advised by Professor Dan Goldwasser from Purdue NLP Group.
