Research Interests

Multiphase Flow and Multi-species Transport in Subsurface Systems
- Multiphase flow (Water, gas, and non-aqueous phase liquid (NAPL)) in the unsaturated and saturated zones.
- Multi-species transport: Toxic organic chemicals, nutrients, and microorganisms.
- Reactions: Physical, chemical, and biological processes in subsurface environments.

Carbon dioxide (CO₂) geological sequestration for the mitigation of anthropogenic climate change


- Flow and transport of CO₂ in deep geological formations.
- Groundwater pollution by CO₂ and companion contaminants due to the leakage of CO₂ injected into deep geological formations.

Water Resources and Subsurface Hydrogeology


- Groundwater flow and contaminant transport.
- Optimization of groundwater use and minimization of groundwater pollution.
- Integrated analysis of surface and subsurface water.

Remediation Technology for Contaminated Soil and Groundwater


- In-situ air sparging, soil vapor extraction, bioventing, and thermal-enhanced venting.
- Monitored natural attenuation and bioremediation.
