Academic Profile

For my undergraduate (integrated master’s degree), I studied Earth Sciences at Oxford, and I graduated with a distinction in 2022. I was an academic scholar at University college, and I was awarded the AWE prize for outstanding performance in Geophysics in 2021. For my master’s project, I explored seismic anisotropic signatures at the Whillans Ice Stream to provide insights into its past and future deformation.

I am co-funded by the Oxford-NERC Environmental Research DTP and the Radcliffe Scholarship from University College.

Current Research

What is the temperature and composition of the lowermost mantle?

Currently, I am working with Dr. Andrew Walker and Dr. Paula Koelemeijer to better understand the physical properties of the lowermost mantle, in particular those of large low wave velocity provinces (LLVPs). LLVPs are two continental-sized structures in the lowermost mantle with lower seismic wave velocities relative to their surroundings, and understanding their physical properties provides insights into the dynamical and thermal evolution of Earth’s interior. I will be using a Bayesian approach to create synthetic Earth models, and determine the optimal model that best agrees with various forms of geophysical data (e.g. seismic tomography, dynamic topography, mineral physics).
