Biogeochemistry Research Group
The overarching aim of the biogeochemistry research group I lead is to understand and help solve complex environmental issues across multi-disciplinary boundaries (soil, water, ecology, human impacts). Research carried out by the group has increased understanding of processes affecting the generation and fate of chemical species and contaminants (e.g. metals, nutrients and organic matter), and how to manage systems to prevent undesirable impacts. Much of our current research is directed to understanding the effects of climate change arising from increasing droughts, reduced river flows, and sea level rise. We are also focussed on developing novel measurement techniques and geochemical models to assist in this area. The group’s research is conducted and linked at various scales; from molecular-level studies in the laboratory, to field-scale experiments, and national-global scale assessments.
Our group has strong collaborations with scientists and agencies in Australia and internationally. We have a proven and extensive track record in delivering complex research advice and outputs to government agencies to assist them to manage environmental issues. Importantly these projects also provide students the opportunity to research and solve "real world" issues, and gain valuable contacts and skills to enhance their future employment prospects. The group is located at the Waite Campus in Adelaide, a stimulating and highly collaborative environment. We make a significant contribution to the University of Adelaide achieving a 2015 Excellence in Research Australia (ERA) Rating of 5 ("well above world standard") in our key areas of geochemistry, soil science, and environmental science and management.
I am Deputy Director of the Acid Sulfate Soils Centre and President of Soil Science Australia (www.soilscienceaustralia.org.au), the peak body representing soil professionals in Australia.
