My research interests are in geophysical fluid dynamics of subsurface multiscale, multiphase, multicomponent, reactive fluid (groundwater, hydrocarbon, CO2) and energy (heat, pressure) transport, such as water- and CO2-based geothermal energy utilization, geologic CO2 storage, grid-scale energy storage, enhanced oil recovery, and groundwater flow. Methods include computer simulations, laboratory experiments, and field analyses.

This professorship and the associated Geothermal Energy and Geofluids (GEG) Group is generously endowed by the Werner Siemens Foundation, which is hereby gratefully acknowledged.
