Paul uses geospatial analytics to understand how and why planets look the way they do. He uses remote sensing, laboratory and numerical modeling and fieldwork in analog sites around the world to examine how volcanic, tectonic and impact processes have shaped planetary surfaces. His interests include exploring what Earth can reveal about other bodies in the solar system––like Mars, Mercury and Earth’s moon––and what these worlds can, in turn, reveal about the history and evolution of Earth.
