I am a field geologist and metamorphic and igneous petrologist interested in mountain building and mineralisation processes occurring along convergent plate boundaries.
Key Research Themes Include:
- Understanding the role of subduction geometry on the thermal and mechanical evolution of the continental lithosphere and how this influences the formation of mineral deposits.
- Improving understanding of the paleostresses and role of shear heating (and transient heating during earthquakes) along the subduction zone interface, and the role this plays in the cycling of volatiles and metals into the mantle wedge or overlying plate.
- Structural, metamorphic and igneous petrological investigations of orogenic belts including the Southwest USA, Scottish Caledonides, and the Cycladic Islands in Greece. The goal of this work is to constrain the time-scales and length-scales of heating during orogenesis and the role this plays in controlling metamorphic dehydration or melting reactions and the rheology of the continental lithosphere.
- Investigating the role of tectonic stress and pre-existing structures have on the generation of natural hydrogen during low-temperature serpentinization.
My approach integrates field-based observations and measurements and geological mapping, with a variety of analytical techniques such as electron probe micro-analysis, thermobarometry and petrological modelling, radiogenic isotopes, electron-backscatter diffraction and U-Th-Pb, Rb-Sr and Lu-Hf geochronology. I am actively recruiting motivated students and I’m seeking future collaborative opportunities. If these topics interest you, please don’t hesitate to reach out and I would be delighted to discuss future potential projects.
