Research

Dr. Song's research interests:

  • Vertical bearing resistance of cantilever sheet piles - numerical modeling and centrifuge testing

  • Bearing capacity of Florida carbonate rocks - high-pressure triaxial testing and numerical modeling

  • Bio-stabilized geotechnics - physical testing and numerical modeling

  • Strain localization and instability in porous geologic materials

  • Mechanics and physics of unsaturated/expansive soil

  • Multiscale multiphysics modeling of porous media

  • Computational chemo and bio-geomechanics

  • High-Performance Computing in poro-geomechanics on HiPerGator

  • Numerical modeling of landslides, subsidence/sinkholes, unsaturated soil liquefaction, subsurface flow, and landfill slope stability

  • Artificial intelligence/machine learning/deep learning in geo-hazard and risk engineering

  • Failure of variably saturated geomaterials under dynamic loads

Dr. Song’s current research focuses on physical, theoretical and computational modeling of multiphysics processes and failure in porous geological materials under environmental loads (e.g., humidity or temperature) and extreme events (e.g., earthquakes or hurricanes). His current research on numerical modeling of multiphase porous media (e.g., geological materials) at multiple space and time scales (nanometers to kilometers and nanoseconds to years) through high-performance computing has a broad spectrum of applications in engineering and science, for example, geo-hazard engineering (e.g., landslides and soil liquefaction), as well as energy, environmental, coastal, and biological geotechnics (e.g., geothermal energy production and storage).

Our research is currently supported by the National Science Foundation, Florida Department of Transportation, and UF HiPerGator supercomputer. We thank them for the support!
