I am a PhD student advised by Professor Jongwuk Lee at Data Intelligence and Learning (DIAL) Lab., SKKU.
I am primarily interested in Information Retrieval and Recommendation Systems. In addition, my research interests broadly lie in the fields of data mining and machine learning in real-world applications.
