Sarah is a hydrogeologist and groundwater modeller. She is currently working on a postdoctoral research project in collaboration with CSIRO on innovative and reproducible approaches to water table mapping. The project is part of the Deep Earth Imaging Future Science Platform at CSIRO, which seeks to develop new and powerful subsurface imaging techniques. Sarah's research is focused on understanding and conceptualising groundwater resources where data availability may be limited. Her multi-disciplinary approach incorporates analytical and numerical modelling, geostatistics, tracer analysis, aquifer testing, uncertainty analysis, and field studies. She is particularly interested in the application of models for decision making.

Prior to starting her post-doc, Sarah completed a PhD with the National Centre for Groundwater Research and Training at Flinders University. This involved studying the influence of hydrogeologic barriers on groundwater flow and age. For part of the time, Sarah was based in Virginia, USA, and collaborated with the United States Geological Survey.

Sarah began her career at Geoscience Australia and worked on many projects including a national assessment of seawater-intrusion, conceptualisation of the Maryborough Basin in Queensland, a study of managed aquifer recharge in Broken Hill, and an assessment of the impact of climate change on groundwater resources in East Timor. At Geoscience Australia, she was in the Groundwater Advice team and regularly worked on advice to the Federal Government about the impact of mining and resource development projects on groundwater resources across the country.

Key responsibilities

Currently, my research is being conducted in collaboration with CSIRO and the Deep Earth Imaging Future Science Platform. I am investigating the process to capture conceptual uncertainty in the process of water table mapping.
