I am broadly interested in why the Earth is such a unique place in the Solar System, and in the role the Earth’s magnetic field plays in shaping our planet. Specifically, I am interested in how geological materials become magnetized, and what they tell us about the evolution of the Earth. My research uses rock and mineral magnetism to study a wide range of geologic processes, from basic geophysics governing the internal structure and dynamics of our planet, to surface processes and geo-environmental history. My approach is inherently multidisciplinary and multi-scalar, combining magnetic analyses (both well-established and non-traditional) with non-magnetic methods.
