Personal statement

Gareth is a geologist with expertise in energy geosciences and engineering. He has experience from both industry and academia in the fields of geochemistry and structural geology applied to carbon dioxide storage and negative emission technologies, geothermal energy, energy storage and oil, gas and mineral production. He enjoys inter-disciplinary research where he brings subsurface expertise and knowledge to wider research engaging with energy and associated waste production in a carbon constrained world.

The architecture and fluid flow properties of shallow fault systems and their implications for geoenergy engineering
Roberts, Jen (Principal Investigator) Shipton, Zoe (Co-investigator) Johnson, Gareth (Co-investigator) McMahon, Christopher (Researcher)
This PhD project seeks to further understanding of fluid flow in the shallow subsurface, and particularly around fault zones, with the aim to reduce risks of geological engineering such as CO2 or hydrogen storage and to inform environmental monitoring. The project involves partners at CSIRO and Geoscience Australia.
