Centre for Microbiology and Environmental Systems Science

The Division of Environmental Geosciences | EDGE at the Centre for Microbiology and Environmental Systems Science | CeMESS investigates key processes controlling the natural environment and anthropogenic impacts.
Researchers at EDGE combine field observations with experimental work, linking molecular-scale mechanisms at environmental interfaces with complex large-scale environmental processes using quantitative modelling.
At EDGE, we accept the challenges posed by the release of known and emerging pollutants and recognise the need to understand their impacts on soils, ground and surface waters, and human health using process-based and mechanistic research.

Understanding the link between socioeconomic drivers and surface water pollution is crucial for protecting aquatic ecosystems and drinking water. Yet,…

Water-soluble polymers (WSPs) like polyethylene glycol (PEG) are common in personal care and household products, but they often enter wastewater…

Nanoplastics in aquatic environments often interact with natural macromolecules, forming what scientists call an “eco-corona.” This eco-corona can…
