Biography

I am the Laboratory Manager for the Geochemistry Cleanroom Laboratory with ~35 active scientists. We analyse a large variety of geological materials including rock, water, soil, sediment, and ice core samples. Our lab is rated class 1000 and comprises ten rooms with a total of 15 laminar flow workstations.

I previously worked as a Research Fellow and Research Associate and have 10 years experience in geological and geochemical research, development of geoanalytical methods, supervision and teaching of undergraduate and PhD students, and public engagement.
