Smart and Sustainable Construction (SSC) Research Group directed  by Dr. Changbum R. Ahn focuses on data-driven techniques and  smart-sensing technologies for analyzing and identifying humans’ collective behavior patterns derived from wearable sensors and/or crowdsourced dataset, in order to design and build (1) safe construction workplaces, (2) smart and connected urban communities, and (3) intelligent and energy-efficient building systems
