Biography

Working in the Basin Structure Group of the Institute of Applied Geoscience at Leeds, my principal research interest is geological controls on fluid movement in the subsurface. Having previous worked in mining and hydrocarbons, these fields often features in my research.

Graduating from an undergraduate Masters in Geology in 2007 I joined Capita Symonds, supporting geoscience work for the Department of Communities and Local Government (then the ODPM). We reveiwed mineral planning policy in the UK (MPS1), specifically with respect the the aggregates industry. After several months I moved to East Africa to work in gold exploration.

In 2010, I commenced an MSc Structural Geology with Geophysics at the University of Leeds. I was recruited onto the BG Group Graduate Development programme in 2010, completing my MSc thesis with them on stress analysis and elastic dislocation modelling in the Santos Basin. Joining them in 2011, I undertook the two-year graduate develoment programme working in Exploration in the South China Sea, the Integrated Reservoir Modelling Team, US Lower 48 Unconventionals Resources Exploration and as a wellsite and operations geologist with the Knarr Development, Norwegian North Sea.

Outside of work, I enjoy multi-day long-distance cycling trips and hold a Glider Pilots Licence.
