Research

Professor, SEOE. My research combines geological field work with geochemical studies that focus primarily on the use of trace element and isotope geochemistry to understand igneous processes. I am particularly interested in understanding how the geochemistry of subduction-related magma is controlled by tectonics in different subduction settings.
