I am an experienced geologist with a keen interest in understanding dynamical, fluid-driven Earth processes. My research currently focusses on experimental measurement of low permeability materials that can be used as barriers to flow. Specifically, my research aims to understand under what conditions low permeability materials can be used as engineered barrier systems for waste disposal (e.g. radioactive waste, landfill, CO2). I have also worked on underground carbon storage and the interaction between two different fluids in a geological reservoir, using analogue experiments to study the dissolution of CO2 into reservoir brines. Research for my PhD centred on the propagation and emplacement of dykes and how this influences the thermal state of the crust. I am also interested in the deformation of the crust on a number of scales, especially in response to fluid injection, and the resultant fracture patterns. I use computational and experimental analogue modelling of these phenomena, applying observations made in the field and the laboratory with those predicted by models.

Current projects and collaborations
- EURAD – A European collaboration working on safe radioactive waste management (including disposal). This project will develop a robust and sustained science, technology and knowledge management programme that supports timely implementation of radioactive waste management activities
- Influence of temperature on clay-based material behaviour (HITEC workpackage of the EURAD project) – Improving THM understanding of clay based materials (host rock and buffer) exposed to elevated temperatures (>100°C) for extended durations. The project will evaluate whether or not elevated temperature limits (100-150°C) are feasible and safe for a variety of geological disposal concepts for high heat generating wastes (HHGW)
- Mechanistic understanding of gas transport in clay materials (GAS workpackage of the EURAD project) – This project will provide data and develop process-level models to improve mechanistic understanding of transport processes in natural and engineered clay materials, including couplings with mechanical behaviour and impact on the clay properties
- Bentonite Mechanical Evolution (BEACON) – This project will investigate the mechanical evolution of an installed bentonite barrier and the resulting sealing ability of the barrier giving a more detailed understanding of material properties and the fundamental processes that lead to bentonite homogenisation
- Renewable Energy StOrage in UndeRground CavErns (RESOURCE) – Project to improve understanding of thermal damage and cavern integrity during rapid pressure cycling
