From June 2014 I have been working within the HydroFrame project - Hydromechanical and biogeochemical processes in fractured rock masses in the vicinity of a geological disposal facility for radioactive waste, funded by NERC's Radioactivity And The Environment (RATE) programme. My role is to help integrate seismic and thermo-hydro-mechanical models for time-lapse monitoring of repository sites.

Until recently I was a Teaching Assistant in the Institute of Geophysics and Tectonics, University of Leeds. My main role was to teach the application of seismic reflection processing as part of the MSc Exploration Geophysics course.

I completed my PhD in Geophysics (Seismology) in 2013. My research used earthquake seismology to look for small scale structures deep in the Earth. I used a combination of array and exploration seismic methods, to construct work flows to analyse teleseismic earthquakes.

I applied my methods to subduction zones in the western Pacific and my results indicated that subducted slabs in this region can keep their crustal component when breaking through to the more viscous lower mantle, to depths of ~1900 km. In addition I used global stacking methods to characterise scattering in the mantle and model for mid-mantle heterogeneity.

Prior to embarking on my PhD, I worked as a Geophysicist, processing marine seismic reflection data for PGS (Weybridge, UK). I worked on re-processing data from the 1980/1990s and combining them into the MegaSurvey+. Additonally I processed new data from Bay of Biscay as well as developing new production work flows for automatic anisotropic velocity picking.
