My primary research interest lies in igneous petrology, geochemistry and stable isotopes. Specifically, this includes:

• Petrology and geochemistry of granites

• Oxygen isotopes in low temperature processes

• Carbon and oxygen isotopes in high temperature processes

• Isotope stratigraphy (Precambrian and Phanerozoic)
