I am an applied structural geologist with a strong interest in the role of fault and fracture networks on sub-surface applications (e.g., CCS) and geo-hazards, with a particular focus on earthquakes and modern day groundwater flow. Additionally, I have a strong interest in the role of objective and subjective uncertainties in geological data collection, and how this propagates through to geological interpretations. During my PhD I used detailed field observations, topological sampling, and photogrammetry to characterise the internal structure of fault zones, and the connectivity of fault-fracture networks, in mechanically stratified rock masses. At a larger scale I used data from multiple sources (e.g., boreholes, mine plans, published geological maps and memoirs, and 2D seismic), combined with my field observations to better understand the geometry and evolution of faults within the UK Coal Measures. In the latter part of my PhD, and post-PhD consultancy work, I applied this knowledge, and combined this with my knowledge of coal mines, to investigate the elements and uncertainties within the mine water reservoir for mine geothermal energy projects. Specifically, I am interested in how uncertainties in post-mining conditions will impact the resource potential of a target mine, and how the risk of these uncertainties may be incorporated into the feasibility stage of a schemes development. My work on the Quake4D project will build on my expertise in subsurface uncertainty, fault structure, and network connectivity to constrain the 3D geometry of inactive extensional systems and quantify subsurface linkage relationships between neighbouring fault strands. This research will be combined with geological field data collected from the Italian Apennines and used to provide inputs for earthquake cycle modelling.
