Biography

I am an isotope geochemist with a wide range of interests in applying geochemical tools to geoscience problems. At Edinburgh I will be making use of the new mass spectrometry facility for isotope ratio and trace element measurements. We will have a multicollector ICP-MS and a high resolution single collector ICP-MS which will be augmented with a laser ablation sample interface. This facility will complement the existing geochemical facilities in the School of Geosciences allowing the school to have a "total geochemistry" capability.

My research has focused on using isotope geochemical tools to learn about Quaternary paleoclimate, specifically looking to constrain the rates and timings of environmental change to place constraints on the behaviour of the earth system.
