I have over 30 years experience in application of numerical modelling to mine design. I am the Director of Business Engagement and Innovation for the Department of Earth and Environmental Science. Prior to joining CSM/the University of Exeter, I obtained industrial rock mechanics experience in South Africa and Botswana. I received a Medal For Excellence from the Institute of Materials, Minerals and Mining in the IOM3 Awards 2020.

My research interests include novel application of state-of-the-art numerical modelling software for evaluation of stress redistribution around both surface and underground excavations, characterization of rock failure and fracturing, and how this can be incorporated into excavation design and simulation of rock mass behaviour. This includes integration of numerical modelling of fractured rock masses with use of both photogrammetry and laser scanning to remotely capture geometry and geotechnical data for innovative three-dimensional modelling of complex slope instability, modelling stress redistribution around both surface and underground excavations, rock failure and fracturing, and how this can be incorporated into mine design.  Recent projects undertaken include discrete fracture network modelling, development of risk assessment methodology for coastal landsliding, modelling of three-dimensional stress redistribution around tunnel face-ends, investigation of factors influencing underground roadway stability under high stress conditions, laboratory investigation into the Kaiser effect, stress induced damage, brittle failure and laboratory evaluation of the effects of mineralogy on the engineering behaviour of altered granites.
