My main interest and expertise is in igneous petrology and in trace element and isotope geochemistry. My science is founded both on laboratory-based analytical studies, as well as on field-orientated observations.
I have had a focus on the development of geochemical analytical capacity at the University of Adelaide.
I have twice been Head of the Department Geology and Geophysics (1995-1998 and 2003).
Currently I am Associate Head of the School of Earth and Environmental Science and head the School’s Post-graduate school (Research Education Committee).
