I'm a catchment scientist and modeler focusing on inter-disciplinary understanding of the effects of land use on multiple ecosystem services, including water quality, freshwater biodiversity, soil conservation and carbon management in catchment systems. Current work focuses on the application and development of statistical, mechanistic and risk-based models to address threats to clean water availability under current the future climate and land use scenarios. I lead research to design and apply water quality models of nutrients, pathogens, pesticides and emerging contaminants, with a special focus on the application of Bayesian Belief Networks as inter-disciplinary system-based decision support tools. I convene an inter-disciplinary research cluster to promote systems thinking and modelling in applied land systems research to support transformative change in socio-ecological systems.
