Researcher Summary

I am a groundwater researcher specialising in the field of coastal hydrogeology. My research includes practical and theoretical work and I engage in a range of methods including analytic and numerical modelling as well as laboratory-scale analysis and field work. I have extensive industry experience in the development of regional-scale groundwater models for groundwater resource assessment. This has informed my teaching by providing me with an understanding of methods that underpin theoretical research in hydrology as well as practical problem-solving of real-world, water resource management issues.

I am passionate about communicating groundwater science to students, resource managers and the local community.

I am interested in supervising Masters and PhD projects that align with my research interests, including seawater intrusion vulnerability, subsea fresh groundwater, braided rivers, groundwater recharge estimation and regional-scale groundwater management.

I am collaborating with research teams in Australia, the Netherlands and Germany. I am also a Research Fellow with Flinders University, Adelaide Australia.

Subject Area: Disciplines

Future Research

  • Characterising seawater intrusion risks in the Canterbury region
  • Exploring surface water-groundwater interactions in braided rivers
  • Quantifying vulnerability of offshore fresh groundwater to anthropogenic impacts
  • Modelling offshore fresh groundwater in the Perth Basin

Key Methodologies

  • Density-dependent flow and transport modelling
  • Analytic and numeric mathematical modelling
  • Laboratory sand-tank experiments
  • Various field techniques
  • Geographical Information Systems
