I use mathematical analysis and computational simulations to understand a wide range of geophysical and environmental fluid flows. I focus on situations in which melting and solidification are significant, such as the generation and transport of molten magma from deep within the Earth, and the formation of sea ice in the Polar Oceans.

Currently, I am part of the FoaLab Laboratory for Geodynamics and work on subduction-zone geodynamics with Prof. Richard Katz. Subduction zones are a crucial part of the Earth’s tectonic system, which controls the cycling of volatile chemicals such as water and carbon on long geological timescales. We are developing physical models of the coupled fluid flow and thermal and chemical transport, and implementing these in open-source simulation code based on PETSc and available for community use.

I am also interested in the interaction between sea ice and fluid dynamics. Sea ice is a sensitive part of the climate system, and is responding dramatically to Arctic warming. I worked as a postdoctoral researcher in the Department of Physics in Oxford University with the group of Prof. Andrew Wells on frazil ice. I studied Mathematics, leading to a PhD on convective flow within sea ice in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge, supervised by Prof. Grae Worster.
