Main Research Field: 

∙ Main Research Directions: (1) Energy and Sustainable Geotechnology, (2) Bio-soil Improvement and Biogeophysics, (3) Coupled Thermo-hydro-chemo-electro-bio-mechanical Processes in Porous Media and Particulate Materials, and (4) Near-surface Geophysical Characterization and Smart Sensor Application.

∙ Methodology: theoretical/experimental studies of particle-level, pore-scale and macro-scale phenomena in particulate materials and porous media (mechanical, chemical, thermal, electrical, hydrological, and biological). Experimentation involves distinct laboratory devices and procedures, with emphasis on low-perturbation wave-based characterization and process monitoring (both elastic and electromagnetic waves), X-ray CT imageries (both micro- and core-scales), and related inverse problems.

∙ Problems: resource recovery (petroleum, natural gas, EOR, methane hydrate, shale gas), geo-environment (geologic CO2 storage, soil remediation), and engineering systems (soil improvement, dynamic soil response, underground excavations).
