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. The global magnetic field is generated by fluid motions in the core, and by studying the structure and evolution of the magnetic field we can understand the dynamics of the core and its interactions with the overlying mantle.
