Research Profile


My group conducts research focusing on the understanding and management of freshwater, with a particular focus on water underneath the ground. This includes water held in the soil, which is essential for plants, and groundwater in aquifers, which can be an important resource for humans. Water that moves through the soil, unsaturated zone and saturated zone can constitute an important part of the hydrological cycle, and can be an important transmission pathway for contaminants.
