About Me

I am a senior researcher in the Data Science Group at Institute for Basic Science, working with Meeyoung Cha. My research interests include predictive analytics with real-world data with temporal, imbalanced, and incomplete in nature. Currently, I am leading a Customs Data Analytics project in collaboration with the World Customs Organization. I obtained my Ph.D. in Knowledge Service Engineering at Korea Advanced Institute of Science and Technology (KAIST), advised by Jae-Gil Lee. My thesis research focused on customer revisit prediction using in-store sensor data.
