Research
I conduct observation-based, multi-disciplinary, meso-scale geological investigations of modern ocean floor and of ophiolites to address the processes of formation and deformation of ocean lithosphere at mid-ocean ridges. Whether on land or at sea I apply fine-scale mapping, structural geology, rock magnetics/palaeomagnetism, petrology, geochemistry and geophysics to answer fundamental geological questions about mid-ocean ridge processes. In the marine realm I have developed methodologies to reorientate IODP drillcore using wireline image logs and hence conduct structural geological/tectonic studies comparable to those applied on land. With the British Geological Survey I have also been prime mover behind the development and application of robotic seabed rock drills to collect directly orientated seafloor samples from hard-rock substrates.
. Current projects include:
- SW Indian Ridge Lower Crust and Moho: drilling the lower crust and Moho at an ultraslow spreading ridge (International Ocean Discovery Program Expedition 360: http://iodp.tamu.edu/scienceops/expeditions/indian_ridge_moho.html)
- Mid-Atlantic Ridge 13°N: multidisciplinary seismic investigation plus near-bottom mapping and sampling of oceanic core complexes to investigate detachment fault processes; also hydrothermal circulation and ultramafic-hosted mineralisation at slower-spreading mid-ocean ridges
- Hess Deep, eastern equatorial Pacific: ROV sampling of the Hess Deep rift valley to decipher magma chamber processes beneath the fast-spreading East Pacific Rise, by means of a petrological, geochemical and microstructural study of a reconstructed lower crustal section
- Oman ophiolite: (1) quantitative investigations of the limits and limitations of the Oman ophiolite–East Pacific Rise analogy; (2) geodynamics of the Oman ophiolite and implications for intraoceanic subduction initiation; (3) magma chamber models and lower crustal accretion mechanisms at fast-spreading ridges
- Troodos ophiolite: (1) structure of the upper ocean crust and relationship between tectonism and magmatism during spreading in the presence of active detachment faulting; (2) transform fault processes, including palaeoseismicity and fluid flow
- borehole core–image log integration for core reorientation, and applications for structural and palaeomagnetic studies with IODP
Some of my fundamental research on seafloor spreading and nature of the ocean lithosphere formed at mid-ocean ridges has been incorporated into the UK National Curriculum in geology for ages 14-18. It is now being taught in geology and geography classes in schools across the UK and worldwide: case studies "a new view of searfloor spreading" and "what is the Moho?", as examples of science in action and hypothesis testing of theories as fundamental as that of plate tectonics itself. I have established a web site "www.seafloorspreading.com" as a resource for teachers to assist them both in delivering the learning materials and in helping convey the practicalities and realities of modern scientific research.
Teaching
I teach classroom modules in general geology, plate tectonics and geodynamics, to undergraduates at all levels, and supervise Masters-level student research projects. I lead geoscience field courses in Cyprus and Great Britain, and supervise geological mapping projects worldwide.

Supervisions
I am interested in supervising PhD students in the areas of:
- mid-ocean ridge processes from the study of modern ocean floor samples and data
- mid-ocean ridge processes from study of ophiolites
- marginal basin processes, 'infant arc' and subduction initiation processes
