O-Joun Lee has been an assistant professor at the Catholic University of Korea, Rep. of Korea, since September 2021. He received his Ph.D. degree in Computer Science and Engineering from Chung-Ang University in 2019 (Supervisor: Prof. Jason J. Jung; Knowledge Engineering Lab). He also received his B.Eng. degree in Software Science from Dankook University in 2015. He was a full-time researcher at Pohang University of Science and Technology, Rep. of Korea, from September 2019 to August 2021. His research interests include graph mining, graph representation learning, and graph neural networks. He has applied graph mining models and methods to various unstructured data, such as social media, bibliographic data, medical knowledge bases, traffic flow data, molecular structures, etc.

I also lead a research group called the Network Science Lab at the Catholic University of Korea (CUK). Network science is a field of study that aims to reveal structural patterns in real-world interaction networks, such as social networks, bibliographic networks, power grids, and others. The Network Science Lab (NS Lab; 네트워크과학연구실), part of the Department of AI at CUK, conducts extensive research on a wide range of theories, methods, and applications related to the collection, representation, and analysis of networked data.
