Senior Research Scientist in Marine Biogeochemistry, University of Tasmania
Research interests:
Chemical oceanography, marine biogeochemistry, trace elements and isotopes, analytical chemistry, ocean iron fertilisation, atmospheric dust deposition
My research has advanced our understanding of marine trace metal biogeochemistry, particularly by focussing on Southern Ocean and Antarctic sea-ice environments. I adopt an Earth system approach and have a broad my understanding of land–atmosphere– ocean interactions and the coupling of terrestrial and marine ecosystems. My current projects address key research questions on atmospheric dust deposition and solubilities, ocean iron fertilisation, physico-chemical speciation of trace elements and their isotopes, and the role of ocean dynamics on chemical and biological marine processes. I have applied my discoveries to important research outcomes related to climate change, ocean carbon sequestration, marine ecosystems dynamics, and geochemistry.
