Biography

I am Reader in Microgeodynamics in the Institute of Geophysics and Tectonics. I gained my first degree in 1975 (Nottingham), M.Phil. in 1979 (Nottingham) and Ph.D. in 1984 (Birmingham). I have acted as Secretary of the Tectonic Studies Group of the UK and Ireland and sat on the Electron Microscopy Committee of the Royal Microscopical Society.

Research Interests

I am a structural geologist with particular interest in microstructural evolution and deformation processes, although I have interest also in the regional geology of SW England, NW Scotland, the western Alps and the NW Himalaya. My early research career focussed on the formation of boudinage and related features, including their usage in strain analysis, and particularly the recognition, measurement, interpretation and significance of crystal lattice preferred orientation (LPO) development in rocks and analogue materials (i.e. metals and ceramics) using electron channelling in the scanning electron microscope. My interest in the latter has continued throughout my career to the present and today involves use of SEM electron backscattered diffraction (EBSD) to characterise the orientation and misorientation characteristics of minerals, rocks, metals and ceramics, from which various petrophysical properties can be derived. My current research therefore involves using petrofabric-derived seismic properties to explain and interpret seismic data in terms of large scale geodynamic processes in both the crust and mantle. I am a founder-member of the LEMAS (Leeds Electron Microscopy and Spectroscopy) Centre, in collaboration with the Institute of Materials Research at Leeds, which provides electron microscopy services to meet both internal and external demands.

Teaching Interests

I teach at all undergraduate levels within the School. Obviously, my main teaching involves structural geology but I teach also computing and statistics as well as mineralogy and petrology. I act currently as the Earth Sciences undergraduate field work convenor, organising all of the undergraduate field and project modules, as well as leading the Level 1 field class to Pembroke and supervising specific final year mapping projects (SW England, NW Scotland). I am engaged currently in developing electronic mapping resources for undergraduate teaching, in collaboration with the School Librarian (Clare Gordon). In addition, I act as the convenor for the School Kennedy Library and University Library representative for Earth Sciences.
