I am a paleomagnetist and stratigrapher. I am interested in approaching questions in Earth Science through (paleo- and rock-) magnetic methodology. I am particularly interested in Earth surface processes and global tectonics through time. I attempt to resolve the interplay between the Earth’s magnetic field, global tectonics, the biosphere, atmosphere and hydrosphere, and their relation to the origin of large mineral deposits through time. Recent work has focused on the mafic magmatic and LIP record of southern Africa. Although my focus is largely on the Precambrian, some Phanerozoic topics also sneak in from time to time.
