Professor Kang’s main research areas are groundwater hydrology and environmental impacts of subsurface-based energy development. Application areas include groundwater impacts and greenhouse gas emissions related to oil and gas development and geologic storage of carbon dioxide. Her current projects involve the development of analytical, numerical, and combined analytical-numerical multi-scale models of multi-phase flow through porous media, field measurements of gas fluxes, and geospatial and statistical data analysis. Fluids of interest include carbon dioxide, methane and other hydrocarbons, and water.
