Research Interests:

My research interests relate to understanding and quantifying the role of hydrothermal circulation through the ocean crust, a fundamental Earth process that is responsible for the transfer of heat from the ocean crust and modifies the chemistry of the ocean crust and the oceans. I use a combination of petrology and geochemistry on samples recovered from ocean crust through scientific ocean drilling to address key questions about the timing, distribution and magnitude of hydrothermal fluid fluxes in the upper and lower ocean crust. I also use calcium carbonate veins precipitated from low temperature hydrothermal fluids as a past record of ocean chemistry. I am now expanding this research to the Semail ophiolite in Oman as part of the ICDP Oman Drilling Project science party. 

Geochemistry techniques:
  • Whole rock and mineral trace elements by ICP-MS
  • Whole rock major elements by XRF
  • Isotope geochemistry (Sr, O)
  • Laser-ablation U/Pb geochronology
  • Electron microprobe

Research Cruises:

IODP Expedition 357 Atlantis Massif Seafloor Processes: Serpentinization and Life, Metamorphic Petrologist
IODP Expedition 335 Superfast Spreading Rate Crust 4, Metamorphic Petrologist
IODP Expedition 327 Juan de Fuca Ridge Flank Hydrogeology, Petrologist (Group Leader)
JC21 Hess Deep Rift
JC7 Mid Atlantic Ridge 13N Oceanic Core Complexes


Research Projects:
  • I have been involved in establishing the onsite core protocols and was onsite in Oman for a total of 6 weeks during Phase 1 drilling operations. 
  • I had multiple roles during the core characterisation program for Phase 1 cores that took place onboard DV Chikyu July-September 2017. 
    • Co-chief scientist Hole GT3A Sheeted/dike gabbro transition
    • Alteration team leader Holes GT1A Hydrothermal fault zones in layered gabbros and Hole GT2A foliated-layered gabbro transition 
    • Staff Scientist Hole BT1B Listvenite-Basal Thrust.  

Ph.D. supervision:
