Research areas
I am a geochemist whose research dominantly focuses on understanding the secular evolution of crustal lithologies and mantle reservoirs on Mars. To do this, I utilise petrological, microstructural and isotopic measurements to investigate the age, magmatic emplacement and subsequent modification (shock metamorphism, low temperature alteration) of martian meteorites. I have also worked on the early Earth, specifically detrital chromite and zircon records, and igneous rocks from other known and unknown planetary bodies.
