Research title: 'Numerical modelling of melting and magmatic differentiation in planetesimals
My main research interests revolve around magma fluid dynamics and computational geoscience.
I previously studied for an MSc by research in Volcanology at Durham university under the thesis title: "Pressure evolution during the recharge of a bubbly magma reservoir". In that project, I used and modified existing numerical models to quantify magma reservoir evolution beneath volcanoes. A 10-minute video summary of my research can be found here.
I have since expanded my area of research to planetary science and geodynamics for my PhD, where I am continuing to develop my strong expertise in computational geoscience.

Planetesimals (up to 100s km diameter) are the earliest rocky bodies in our solar system. The collision of planetesimals formed the modern planets in the inner solar system. It is thought that the internal structure of the colliding planetesimals affects the development of the planets. Therefore, the internal evolution in planetesimals is an important part of our solar system's evolution. Most of our understanding of planetesimals come from meteorite observations. However, as they only represent a tiny fraction of a much larger planetary body, it is impossible to fully constrain global scale processes. Therefore, it is important to conduct physical experiments and develop plysics-bases numerical models to infer global-scale processes from small-scale meteorite observations.
