I do research on sequence modeling with machine learning. In particular, I am interested in developing reliable generative models for language, music and dance. Most recently, I was a visiting scholar at SNU Music & Audio Research Group (advisor: Kyogu Lee), an AI resident at NAVER Clova (advisor: Minjoon Seo), and a research intern at SNU Vision & Learning Lab (advisor: Gunhee Kim).
