Biography
I use paleomagnetic and rock magnetic techniques to investigate a wide variety of geological problems, including distributed deformation at collisional plate boundaries (e.g. Hikurangi Margin, New Zealand), paleogeographic reconstructions (Neoproterozoic of Oman), and past behaviour of the Earth's magnetic field (Archean Pongola Supergroup, S Africa). My current work aims to use magnetic fabrics to measure paleostrain and map ancient deformation fields. I am particularly interested in interactions between the deep mantle and surface tectonics, such as how the migration and spreading behaviour of the East Pacific Rise seems to be linked to a long-lived upwelling from the core mantle boundary.
