About Me

I'm a professor in Dept. of Computer Science and Engineering, Graduate School of AI, and Dept. of Applied Data Science at the Sungkyunkwan University from September 2019. Before I joined the faculty at Sungkyunkwan University, I worked at Dong-A University from September 2004 after completing my Ph.D in August 2003.

I work at the intersection of natural language processing (NLP) and information retrieval (IR) based on Language Models, and I am interested in NLP (dialogue system, question/answering system, etc.), IR (generative IR, etc.), Generative AI (controllable text generation, etc.), and Text Mining (text classification/summarization, sentiment classification, etc.). Recently, I'm interested in how to develop and utilize sLM (small Language Model) and RAG (retrieval augmented generation) for my research areas. I'm leading the Natural Language Processing (NLP) Laboratory at College of Computing and Informatics of Sungkyunkwan University. I worked at the Computational Linguistics and Information Processing Laboratory (CLIP) at the University of Maryland, College Park as a visiting scholar from 2011 fall semester to 2012 spring semester. My collaborator was Prof. Doug Oard.
