My research focuses on Geochemical Modeling and Reactive Transport Simulation for CO₂ Geological Storage and Subsurface Energy Systems. In this project, I investigate the coupled physical and geochemical processes that control fluid–rock interactions during CO₂ injection into deep geological formations.

At the pore and core scales, I use geochemical speciation and reaction-path modeling to study mineral dissolution/precipitation, ion exchange, and scaling reactions triggered by acidified CO₂ plumes. These models help predict changes in porosity, permeability, and wettability, critical parameters for long-term storage security.

At the reservoir scale, I integrate reactive transport modeling with multiphase flow simulation to track CO₂ migration, trapping mechanisms, and geomechanical impacts. This includes developing coupled PHREEQC–ECLIPSE/MATLAB workflows to simulate how geochemical reactions evolve over time and affect reservoir properties.

Ultimately, my work aims to improve the predictive capability and safety assessment of subsurface CO₂ storage projects, and to provide a foundation for applying similar approaches to emerging technologies such as underground hydrogen storage (UHS) and subsurface energy systems.

My research interests include:

• CO₂ geological storage (CCS / CCUS)
• Underground hydrogen storage (UHS)
• Multiphase flow and reservoir simulation
• Reactive transport in porous media
• Data-Driven and Physics-Based Modeling for CO₂ Storage and Reservoir Simulation
