I'm a Principal Research Scientist in CSIRO Land and Water's Aquatic Ecology Monitoring and Assessment Team, where I lead research relating to the ecology and population dynamics of freshwater and estuarine fishes, and management of aquatic ecosystems. I have worked extensively on freshwater and estuarine ecosystems throughout south-eastern Australia. My current research involves the impacts of river regulation on native and invasive fishes to inform water resource management and aquatic ecosystem conservation. I am currently undertaking large-scale, collaborative research projects on fishes throughout the Murray-Darling Basin (MDB), including the Coorong estuary. These projects are using telemetry, otolith chemistry and demographic data to understand the ecology of fishes and spatio-temporal scales of population dynamics. This research is aiding fisheries and water resource management, including environmental water allocation.
