Planetary geologist, and postgraduate DPhil student working with the Paleomagnetism Group under Claire Nichols. Research primarily investigates late-stage planetary processes through paleomagnetic and cosmochemical analysis of the Eagle Station and Pyroxene pallasites (ultra rare stony-iron meteorites) following previous work done on the Main Group pallasites. The “Cloudy Zone” (micro- and nanostructures formed within the Fe-Ni matrix) of pallasites has been shown to preserve magnetic field signatures with high efficacy, suggesting an active dynamo at the time of their formation. By understanding the paleomagnetic signatures within cloudy zone structures, as well as the isotopic and elemental compositions of these pallasites, we can explore how late-stage planetary processes and the (still debated) formation of pallasites were influenced by core size, oxidation state/chemical composition, impact events, and their spatial locality in the early solar system. This research is generously funded through a Science and Technology Facilities Council Studentship award.
