Brett is an environmental scientist with over 12 years of consulting and research experience. Brett has a full time position with the University of Adelaide's Acid Sulfate Soil Centre (Biogeochemistry Research Group).Current research and consulting areas include:- Assessment, management and remediation of Acid Sulfate Soils and Acid and Metalliferous Drainage- Inland and coastal Acid Sulfate Soil landscape mapping- Impacts of drought and climate change on water and soils- Wetland soil and water biogeochemistry- Contaminated land assessment and managementThe ultimate aim of the group is to understand and assist clients to 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. 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.We have a proven and extensive track record in delivering complex research advice and outputs to industry and 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 the future employment prospects of students / collaborators. The group is located at the Waite Campus in Adelaide, a stimulating and highly collaborative environment.
