Principal Investigator


Jinhyun Choo

Jinhyun Choo is an Assistant Professor of Civil Engineering at The University of Hong Kong (HKU). He obtained his Ph.D. from Stanford University, under a Fulbright Scholarship, in Civil and Environmental Engineering (Geomechanics) with a minor in Mechanical Engineering. He then completed a year of postdoctoral training at Columbia University before joining the HKU faculty. In earlier days, he received his B.S. and M.S. degrees from Seoul National University in South Korea, and worked for three years at the Korea Institute of Civil Engineering and Building Technology. 

Choo 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. He has been elected to be a member of the Computational Mechanics and Poromechanics committees of the Engineering Mechanics Institute (EMI) of the American Society of Civil Engineers (ASCE). He is also a member of three technical committees (Numerical Methods, Geomechanics from Micro to Macro, and Energy Geotechnics) of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE).

Team Members


Fan Fei

Fan Fei joined the group in 2018 as a Hong Kong PhD Fellow, after receiving his B.S. degree in Civil Engineering at HKU with first class honours. Throughout his undergraduate years at HKU, he was in Dean's honours list every academic year, and received several prestigious awards including a C.L. Tse Prize in Civil Engineering and a Leung Ting Kui Scholarship. His PhD research focuses on the development of computational approaches to investigate fracture, damage, and other inelastic deformations of underground rocks subjected to complex structural and environmental loads.


Shanghui Yang

Shanghui Yang joined the group in Fall 2018 as a PhD student. She obtained her B.S. and M.S. degrees in Hydraulic Structure Engineering at Wuhan University. During her time at Wuhan, she received multiple prestigious scholarships as well as Third Prizes in the 2015 China Post-Graduate Mathematical Contest in Modeling and the 2017 National English Competition for College Students. Her current research interests include mathematical modeling of the time-dependent responses of geologic materials.


Yidong Zhao

Yidong Zhao has been working with the group since Summer 2018, first as a HKU Civil Centennial Future Scholar and then as a Research Assistant. Currently he is pursuing his M.S. degree in Architectural Civil Engineering at Tongji University, where he also earned his B.S. degree as a Shanghai Outstanding Graduate in 2016. He has been the winner of China National Scholarships (two times), a National Second Prize in the 10th Zhou Pei-Yuan Mechanics National College Competition, and a First Prize in the 1st Mechanics Competition of Shanghai, among others. His work in the group focuses on computational geomechanics problems involving large inelastic deformations.


Junwei Zhang

Junwei Zhang started working as our group’s Student Research Assistant in January 2019. He is currently an undergraduate student in the Department of Civil Engineering in HKU. His research work focuses on analyzing opportunities for geologic carbon utilization and storage in the production of unconventional energy resources in China.
