Research interests

My primary research interest lies in investigating the composition of Earth and the evolution of the mantle through-out geological time. Within this general premise, my research focuses on both terrestrial and extra-terrestrial samples. From looking at the initial building blocks of Earth, through ancient melting events on Earth, to modern day melt genesis. This is achieved through a number of different isotopic systems, including both long-lived and short-lived radionuclides, for which the development of high precision trace element and isotopic measurements is a fundamental aspect.
