Our group uses micromechanics, micro-scale imaging videography, fundamental theories, and numerical simulations involving coupling between the Discrete Element Method and computational fluid dynamics (DEM-CFD) to better understand coupled processes in geomechanics at the relevant constituent scale. Examples are hydro-thermo-mechanical coupled processes in rock; particle-fluid multiphysics, flow and transport in geomechanics and mudflow mixture particle-air-water composition behavior.

Currently funded topics include

  • Post-wildfire mudflows
  • Enhanced Geothermal Systems (EGS) and hydrocarbon georeservoirs   
  • Seismic soil-structure interaction of precast concrete earth retaining walls

  • : Big news! Our experiment boarded sucessfully to ISS, on hydrophobic sand-water-air mixtures flow and transport. Super excited, read and listen more on the links below.
  • : More graduates are out of my lab!
  • : Busy summer in the lab!
  • : My lab members have won quite a few awards in recent years! Excited for the hard work recognition and a chance to disseminate our research more broadly!!! Click here to see the award list
  • : Preparations to send our experiments to the International Space Station (ISS) are on the way! Wenpi Ma and Space Tango are working tirelessly to prepare some fun science! We also learned that our "cube" is likely going to be "shipped" up with NG-18!
