Hello! I am a machine learning researcher with previous experience in quantitative trading (2.5 years) and natural language processing (6 years). I obtained PhD in CSE from Seoul National University where I was advised by Prof. Gunhee Kim and supported by Google PhD Fellowship and NAVER PhD Fellowship.
