Prof. Swanson-Hysell is an Associate Professor in the Earth and Planetary Science Department at UC Berkeley. His research develops quantitative constraints on the long-term evolution of Earth through integrating geophysical and geochemical data sets that are developed within a rigorous geologic context. A major focus of this work is on paleomagnetic and rock magnetic data sets, often from stratigraphic sequences, that his group develops in order to test hypotheses about the migrating positions of continents (paleogeography), changes to the surface environment (particularly planetary climate change), and the evolution of Earth's magnetic field. Hypotheses abound in Earth science related to major transitions such as the reorganization of continental blocks into and out of supercontinents and the initiation and terminations of ice ages including global glaciation. Swanson-Hysell's research seeks to bring quantitative constraints to such changes, including their timing and rates, in order to test such hypotheses and further understanding of Earth's long-term evolution. Of particular relevance to the Tonian-Cryogenian boundary, is the research Swanson-Hysell has pursued on volcanic and sedimentary rocks of that age in northern Ethiopia that has resulted in calibrating stratigraphic records in the lead-up to Sturtian glaciation.
