Research Interests

Understanding the chemical differentiation of the Earth places key constraints on the transfer of material between the mantle and crust, chemical variability in basaltic magmas, and ultimately, the habitability of our planet. My research seeks to constrain mechanisms of chemical differentiation and variability in basaltic melts associated with mantle plumes. I use a multi-elemental approach (i.e., almost the full periodic table) to try and understand how the properties of the system (e.g., pressure, temperature and fO2) affect chemical variability and mobility. I also use simple numerical models to understand how signals of chemical variability in the Earth's mantle are preserved during melt transport and subsequent eruption.
