Dr. O Kim is an Associate Professor at Korea University, specializing in the spatial dimensions of aging and environmental health. A trained geographer and demographer, O Kim utilizes machine learning and spatial methods to model the collision of climate risks and demographic transition. His research identifies critical vulnerabilities in East Asia's aging societies, projecting that elderly exposure to extreme heat will quadruple by 2060 in South Korea.
