Groundwater Hydrogeology & Geologic fluids Group focuses on environmental, climate change, and energy related research such as geologic CO2 sequestration, groundwater hydrology, and geothermal energy development with an emphasis in multi-phase phenomena, reactive transport modeling, and heat transport. The methods we prefer range widely, from analytical and numerical approaches to field applications. Thus, research includes interdisciplinary approaches, integrating elements of groundwater hydrology, hydrogeochemistry, geology, thermodynamics, and petroleum engineering.
