Research Interests
My research interests place me within the Deep Earth Research Group of the Institute of Geophysics and Tectonics.
My primary research focus is the dynamics of the core-mantle system. Observed oscillations of the fluid and solid cores provide insight into properties such as the strength and morphology of the magnetic field within the core, the viscosities of the fluid and solid cores, the shape of the inner core and core-mantle boundaries, and the conductivity of the lowermost mantle. Core oscillations can be detected using observations of magnetic field variations, changes in length-of-day and polar motion, and changes in the gravity field. Current research in this area is being carried out via two NERC funded research projects, which supports the post-doctoral work of Dr. Luis Silva, and PhD students Will Brown and Grace Cox.
I also maintain research interests in deformation of the lithosphere in relation to surface mass loading such as glacial isostatic adjustment. This work includes the NERC PhD studentship of Luke Jackson.
Teaching Interests
My Deep Earth research interests contribute directly to my undergraduate teaching in modules such as Global Geophysics and the final year Independent Research Modules.
I also contribute to the teaching of methods such as gravity, magnetics, resistivity and GPR in undergraduate Applied Geophysics and master's Near-Surface Geophysics modules and field trips.
