Welcome to the SURE3 Geotechnical Engineering Research Group

Our research group aims to develop countermeasures against global climate change threats and accompanying geotechnical engineering hazards, through multidisciplinary convergence for the sustainability and eco-resilience of our Civilization.

In particular, we focus on SURE3 geotechnical engineering, where 
SURE3 stands for Sustainability
urban UtilizationResilience

EnvironmentalExtreme, and Emerging geotechnical engineering

Please join us for various research activities including Bio-soil studies, Soil preservation and erosion control, Hydro-geotechnology,
Anti-desertification, Soil treatment and ground improvement, Underground construction, and other emerging geotechnical engineering fields.
