Hello! I am currently a PhD candidate in the Computer Science & Engineering Department at Korea University and a member of Data Mining and Information Systems (DMIS) Lab, advised by Prof. Jaewoo Kang (and co-advised by Prof. Hyunwoo J. Kim for a year). During my PhD course, I completed the Intensive Artificial Intelligence Program at Carnegie Mellon University and studied as a visiting student advised by Prof. Leman Akoglu. I worked as an AI research intern at KakaoBrain for six months (hosted by Eun-Sol Kim, Ph.D.). Prior to my PhD studies, I received a Bachelor's degree in Biomedical Engineering from Korea University.
My research area covers the broad field of machine learning, with a focus on representation learning for graph-structured data. I am also interested in applying machine learning techniques to diverse domains, including computer vision and bioinformatics.
