Graduate student opportunities in petrology and geochemistry: I am always keen to hear from enthusiastic and questioning prospective graduate students. Current areas of interest include, but are not limited to:
• The formation and cooling of the oceanic crust and lithosphere.
• Hydrothermal circulation in the oceanic crust and its impact on seawater chemistry.
• The thermal evolution of Earth's crust and mantle.
• Global geochemical cycles.
