Researcher biography
Dr. Ryan Turner is currently the Science Leader of the Reef Catchments Science Partnership at the University of Queensland (a partnership with the Department of Environment and Science). Ryan was previously the Principal Scientist for Water Quality and Investigations in the Department of Environment and Science and held an Adjunct Associate Professor role at Queensland University of Technology in the Managing for Resilient Landscapes, Institute for Future Environments. For 12 years Ryan managed multimillion dollar water quality monitoring programs assessing the impacts of sediment, nutrient and pesticides loads in numerous catchments along the Queensland coast discharging to the Great Barrier Reef and Moreton Bay. Ryan has been on several steering committees and technical advisory panels, such as the Great Barrier Reef Foundations Technical Advisory Panel. He has published extensively (>60 papers and reports) and led several Queensland Government – Academic collaborative research projects. Ryan previously supervised analytical chemistry and microbiology laboratories in the private and public sector. Ryan has developed numerous methodology and standard operating procedures for analytical and monitoring techniques (water quality, sediments and soils). Ryan's passion for the future of water security is what keeps him going.
