Biography
I completed a MSci degree at University College London between 2015 and 2019 where I developed my passion for geology and understanding the natural world. I am primarily interested in hard rock geology with a focus on geochemistry and petrology. My first research project investiagated the origin of Cornish Granitic Pegmatites. I used a range of petrological and geochemial techniques, including fluid inclusion analysis to understand the formation history of my samples.
I moved to Bristol in 2019 to start a PhD in mantle isotope geochemistry. My research primarilly focused on using novel stable isotopes to investigate the processes of crustal recycling and the generation of chemical heterogeneity in the mantle. The main "stable" isotope systems I worked with were, Uranium, Molybdenum, and Potassium. I worked on a variety of geologic samples to tackle various research questions, such as the onset of deep ocean oxygenation; alteration of the oceanic crust; global variations in MORB; N-MORB vs E-MORB geochemistry; subduction zone processing.
I am now a postdoctoral research focusing on expanding our database of global MORB measurments to investigate the degree of chemical heterogeneity in the upper mantle. My work is part of a larger project, MC2 - Mantle convection constrained, which aims to use geochemial and geophysical constraints to develop geodynamic models of mantle convection over the past one billion years.
