Aquatic Chemical Processes Group (ACPG)
The Aquatic Chemical Processes group is interesting in understanding the fundamental chemical mechanisms that drive biogeochemical processes in natural and engineered aquatic systems. Our work combines laboratory experiments under carefully controlled conditions to isolate and resolve specific chemical processes, kinetic modelling to understand and interpret the mechanisms involved, and field measurements to explore the importance of these processes in a range of different environments. We make use of a wide range of conventional and novel techniques, such as spectrophotometry, electrochemistry, synchrotron-based X-ray spectroscopy, neutron scattering, and high performance computing. The types of projects we undertake include investigating the bioavailability of iron to marine cyanobacteria, resolving the pathways by which dissolved metal ions combine to form minerals, understanding the photochemistry of natural surface waters, and investigating the role of redox processes on nutrient availability in the rhizosphere of plants.

Environmental Biogeochemistry and Mineralogy Group (EBMG)
Members of the Environmental Biogeochemistry and Mineralogy group study biogeochemical and mineralogical controls on iron, sulfur and contaminant dynamics in soils, sediments and aquatic systems through field studies, laboratory experiments and modelling. The research findings have application in preserving and improving soil, sediment and water quality and in the rehabilitation of degraded landscapes. More on EBMG
Geoarchaeology and Archaeometry Research Group (GARG)
The Geoarchaeology and Archaeometry Research Group (GARG) at Southern Cross University focuses on the interaction between past human populations and their environment at the time.
Our aim is to use and enhance methods and analytical techniques from mathematics, chemistry, physics, earth sciences and life sciences to answer a broad range of questions in geoarachaeology and archaeometry, including (but not limited to) stone tools sourcing, timing of human evolution, palaeoenvironmental reconstructions, palaeodiet, site formation processes and occupation history, as well as characterisation of archaeological finds.

Landscape Hydrogeochemistry Group (LHG)
The Landscape Hydrogeochemistry Group explores geochemical and hydrological processes that control water quality and sediment geochemistry and at a landscape-scale.
The groups research embraces diverse landscapes, ranging from floodplain and estuarine wetlands to head-water streams and spans the mineral-water interface through to sub-catchment scale processes.
We are particularly interested in the co-cycling of major elements (Fe, S, C) and trace elements such as arsenic in aquatic and terrestrial environments with dynamic redox conditions.
The group works closely with industry, state and local governments and has helped develop, assess and refine a variety of techniques for remediating highly degraded acid sulfate soil wetlands. More on LHG
