Hi, I am Jeongwon(they/them)
Ph.D student at Human-centered Intelligent Systems Lab (HIS Lab), POSTECH
A truly sustainable daily life requires both the inner sustainability of individuals and the sustainability of their surroundings. I design computing-driven interventions toward both, with a focus on environmental issues and personal well-being. I am at HIS Lab, POSTECH, advised by Prof. Inseok Hwang.
