Kanghyeok

Hyunsoo Kim


Dr. Hyunsoo Kim is a postdoctoral associate of the Smart and Sustainable Construction Research Group at the University of Nebraska-Lincoln. He received his BS. MS, and PhD in Architectural Engineering at the Seoul National University in South Korea. He has studied construction safety management since 2008. Hyunsoo's research in UNL focuses on human objects and their behaviors. Especially, construction hazard identification by analyzing human objects and their behaviors collected from single or multiple sensors is his main research area. When he is not conducting research, he likes to go hiking at mountains. His major concern is that there is not a mountain for hiking nearby Lincoln.
