Earth System Petrology (ESP) was originally established during Charles Lesher's Niels Bohr Professorship (2013-2018). Collaborative efforts established during the professorship continued and now ESP is encompassed in the Deep Earth sector at the Aarhus University Geoscience Department. The team of researchers is dedicated to understanding our planet’s dynamics and evolution by coupling magmatic, structural, topographic, and climatic observations at the Earth’s surface with our growing knowledge of deep mantle and lithosphere processes.
