Yoonjung Han joined the group as a PhD student in January 2020. She received an M.S. degree from Seoul National University of Science and Technology, where her research centered on the properties of fiber-reinforced concrete and light-transmitting concrete. Afterward, she worked in a research center for two years, where she investigated lightweight concrete in addition to continuing her investigations of fiber-reinforced concrete and light-transmitting concrete.As a member of this research group, she is focused primarily on computational modeling and experimental analysis of microstructure development and properties of concrete binders.
