Stephanie has focused on volcanic and magmatic activity throughout her career, first investigating Icelandic volcanoes using campaign GPS for her MSc (Wits, 2009); and then sills and dykes of the Karoo LIP using aeromagnetic and historic seismic data for her PhD (Wits, 2015). For her PhD she also created a 3D model of the Karoo Basin, constrained by potential field, seismic, borehole, petrophysical and teleseismic data. She has also conducted investigations into the western and southern lobes of the Bushveld Complex using 2D and 3D seismic data and aeromagnetic data. She is currently lecturing at the School of Geoscience at Wits University.
Stephanie has been on the SAGA committee since 2015 and the SAGA conference organising committee in 2017 and now in 2019.
