Research Interests

I am interested in understanding how hydrologic systems function, specifically the groundwater component. My research areas include groundwater dynamics in coastal regions, groundwater - surface water interaction, and landscape restoration. I characterise field systems using various methods and parameters including pressure, conductivity and natural tracers. I test processes and perform sensitivity analyses using analytic, numeric and physical modelling. I hold a Research Fellowship with Flinders University, Australia and am an Associate Editor for Hydrogeology Journal.
I am Principal Investigator in the following MBIE Endeavour research programs:
* Subsurface processes in braided rivers - hyporheic exchange and leakage to groundwater (2019 - 2024)
* Transforming coastal lowland systems threatened by sea-level rise into prosperous communities (2021 - 2026)
