My research focusses on heat transport mechanisms in groundwater. I am particularly interested in the conditions under which the assumption of local thermal equilibrium is valid for describing heat transport on the field scale.

Focus Areas:

Local thermal (non-)equilibrium, advective heat transport, heterogeneity, shallow geothermal energy
