The Soga Research Group carries out research in the field of geotechnical and infrastructure engineering. We are interested in developing new monitoring technologies, which allow gaining insight into the behavior of infrastructure, detecting anomalies, and providing data for performance analyses. On top of that, we are also conducting research on city-scale modeling and simulations to evaluate the value of sensing for better management of infrastructure during operation as well as for better response during and after natural disasters such as earthquakes and wildfires. Our research groups are divided into four sub-categories as follows.
The group conducts research in the field of computational geomechanics utilizing a variety of methods that include the Material point method (MPM), Finite element method (FEM), and Lattice element method (LEM). The group applies these methods to both research and consulting applications which include, but are not limited to landslides, slope failures, tunneling, soil-pipeline interactions, geothermal energy, and deep borehole drilling.

The sensor technologies and methodologies are developed to transform the future of infrastructure and geomechanics through smart information. The data gathered permits an assessment of the behavior of the infrastructure in its environment and allows performance analyses. The group develops, tests, and delivers new robust, resilient, and adaptable technologies, such as distributed fiber optic sensors (DFOS), wireless sensor network (WSN), energy harvesting, and computer vision. … Read More »Sensing Technology
