Career Research Highlights
Bob’s main research interests lie in the study of the structure, mechanics and transport properties of weak fault zones using fieldwork, microstructure and rock deformation experiments. Together with Nicola De Paola and Stefan Nielsen, he has recently established the Rock Mechanics Laboratory in the Earth Sciences Department at Durham. He has also pioneered studies of fractured basement reservoirs and the role played by pre-existing structures in controlling crustal deformation patterns at all scales. His international expertise in these areas has led to significant industry funding for his research, most notably in work related to the Clair oil field, the largest remaining asset in the UKCS. He also provides expert advice to the nuclear industry (new builds, geological disposal of waste) and is a member of the Office of Nuclear Regulation (ONR) Expert Panel in Seismic Hazard and Climate Change, contributing expertise on reactivation and capable faulting in the UK.
Bob has published 174 peer-reviewed papers and has edited 12 books. Since 2001, he has obtained research funding in excess of £2.9 Million. He is a former Head of Department (twice) and NERC KE Fellow.
