Staff profile

I am a geochemist with strong research interests in isotope geochemistry as a tool to address scientific questions from melt generation to surface environmental pollution. My research uses state of the art multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) and thermal ionisation mass spectrometry (TIMS), supported by an extensive suite of clean labs for elemental separation in materials from rocks to soils to water.
