Justin’s major research field is the quality of source water for potable supply and river and lake ecology. He also leads a large research project on the treatment of reuse water using biofiltration. The importance of water to Australia and Internationally with the threat of climate change and a drying climate mean that my skills are in demand for research, consulting and educating the next generation of water scientists. He has broad research interests in limnology and water treatment. Primary research focus is coupling between hydrodynamics, biology and water quality contaminants such as cyanobacteria and pathogens. Currently leads several large inter-institutional projects examining degradation of chemical contaminants of concern (endocrine disruptors, pharmaceuticals), carbon cycling in lakes and rivers and the ecology of the Coorong and Lower Lakes of the River Murray.
