Research: Seismological studies of Earth's inner core
Earth's inner core is the deepest region of our planet; despite it's location under our feet it was not discovered until after the dwarf planet Pluto. The inner core stabilises the Earth's geodynamo - the source of Earth's magnetic field. The core segregated from the rest of the planet early in Earth's history; properties of the core can provide information about the conditions at the centre of the Earth now and billions of years ago.
I use both body wave observations and normal mode oscillations to study the structure of Earth's inner core, in particular the presence of velocity anisotropy. By combining these two techniques, I hope to better understand both the large and small scale structures in the inner core.
My PhD research was funded by a NERC studentship, a CASE award from Schlumberger and a Research Scholarship and Research Grant from Trinity College, Cambridge. I am a member of the Institute of Theoretical Geophysics and the Deep Earth Structure and Global Seismology group in Cambridge. Together with Ed Nissen, I am responsible for organizing the Bullard Laboratories Colloquia. If you have any suggestions for future speakers, please contact me.
