Leanne’s research focuses on coastal hydrogeology, groundwater-surface water interaction, and water resource management. Her work addresses risks to water security in coastal zones including seawater intrusion, as caused by groundwater extraction and climate change. Current projects span a number of settings including offshore aquifers, shallow aquifers adjacent to tidal estuaries and coastal lagoons. Leanne employs various field methods in combination with variable-density groundwater flow and transport modelling to provide insight into physical processes and optimal water resource management. Recently, Leanne's research has extended to surface water-groundwater interaction in braided rivers. She is an Investigator in the MBIE Endeavour funded project: Subsurface processes in braided rivers – hyporheic exchange and leakage to groundwater. Additionally, she is collaborating with research teams in Australia, China, the Netherlands, Germany and USA on various projects. She holds a Research Fellowship with Flinders University, Australia and is an Associate Editor for Hydrogeology Journal.
