Biography

Ryan Orr is a chemist and soil scientist with experience in the commercial laboratory and university sector. Currently his research is focused on minimizing the impacts of Panama disease in North Queensland by managing soil abiotic characteristics. In particular this research is investigating the use of fertilisers for micronutrient control.

After completing a BSc. in Chemistry with the University of Victoria in Canada, Ryan undertook an MSc. at James Cook University in Environmental Earth Science. His research focused on the prediction of soil organic carbon content in Papua New Guinean soils using infrared spectroscopy. He, supervised by Associate Professor Paul Nelson, is currently part of a multiorganisational attempt to combat Panama disease in the Australian banana growing industry.
