Overview


I investigate zoning and chemical heterogeneity in crystals using microanalytical geochemistry to improve how geoscientists “read minerals” in order to interpret the geological record. As well as conducting research, I am equally passionate about sharing my fascination with the Earth’s processes through tertiary education and public engagement. I aim to improve the gender balance in my discipline through positive actions.

Research Overview


  • My research expertise is in micro-scale mineralogy, at the intersection between geoscience and analytical chemistry. I use in situ analytical techniques to elucidate the chemical complexity of minerals, to improve the way geoscientists measure and interpret minerals in the geological record.
    Current highlights include:

    • Leading the development of novel techniques to map mineral chemistry at unprecedented resolution using TOF-SIMS and QEM-EDS.
    • Developing a new mineral-scale proxy to estimate historical trace element fluxes in Earth's oceans on millennial timescales.
    • Leveraging big data to provide new insights into geoscience. For example, I have used mineralogical databases with >90,000 analyses to document systematic chemical offsets between volcanic and plutonic minerals. I have also analysed global earthquake catalogues documenting Earth's deepest earthquake swarms to discover new insights into fluid/melt migration above subduction zones (see the video in the bottom right-hand corner of this page).
