Hello! I earned a Ph.D. in Computer Science from Korea University, where I was a member of the Data Mining and Information Systems (DMIS) Lab advised by Prof. Jaewoo Kang (and co-advised by Prof. Hyunwoo J. Kim for one year). During my PhD course, I completed the Intensive Artificial Intelligence Program at Carnegie Mellon University and spent time as a visiting student under the supervision of Prof. Leman Akoglu. I worked as an AI research intern at LG AI Research for nine months (hosted by Soonyoung Lee, Ph.D.), and at KakaoBrain for six months (hosted by Eun-Sol Kim, Ph.D.). Prior to my PhD studies, I earned a Bachelor's degree in Biomedical Engineering from Korea University.
My research area encompasses 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.
