Hyeokjin is a Research Fellow at the Fetal-Neonatal Neuroimaging Developmental Science Center (FNNDSC) at Boston Children’s Hospital, Harvard Medical School. He obtained his PhD in Electronic Engineering from Hanyang University, South Korea, in August 2024. During his doctoral studies, his research primarily focused on graph neural networks for analyzing various graph-structured data based on multimodal brain imaging. At FNNDSC, he has been working with Dr. Kiho Im focusing on analyzing abnormal patterns in congenital heart disease using sulcal pattern graphs extracted from structural MRI-based surface models. Extending this work, he currently aims to develop deep normative modeling of sulcal pattern graphs through unsupervised learning to apply to various disorders.
