I'm a Ph.D. candidate at Machine Intelligence Lab. at Seoul National University. I am advised by Prof. Kyomin Jung at Dept. of Electrical and Computer Engineering. Before coming to SNU, I was a senior software engineer at Samsung artificial intelligence (AI) research center.

My research interests are in the areas of machine learning and natural language processing (NLP). In particular, I am interested in the question-answering system and emotional dialogue model.

Keywords: NLP, Machine Learning, Artificial Intelligence
