Jinhyun Choo is Assistant Professor of Civil Engineering at The University of Hong Kong (HKU). He specializes in geomechanics and geotechnical engineering, and their intersections with computational solid mechanics and flow in porous media. His work addresses subsurface-related problems in the areas of civil infrastructure, energy resources, and environmental sustainability.
Dr. Choo obtained his Ph.D. from Stanford University, in Civil and Environmental Engineering (Geomechanics) with a minor in Mechanical Engineering. He then completed his postdoctoral training at Columbia University before joining the HKU faculty. In earlier days, he received B.S. and M.S. degrees from the Seoul National University in Korea, and worked for three years at the Korea Institute of Civil Engineering and Building Technology.
Dr. Choo is the recipient of multiple prestigious awards, including a Fulbright Scholarship for doctoral studies in the United States, and a Charles H. Leavell Fellowship from Stanford University for research on sustainable built environment.
