Jason Sharples is a mathematical scientist at the University of New South Wales (UNSW), Professor of Bushfire Dynamics and Director of UNSW Bushfire. As an internationally recognised expert in dynamic wildfire behaviour and extreme wildfire development, his research has extensively influenced policy and practice in Australia and internationally. He uses advanced mathematical and computational models to understand the dynamics of wildfire propagation and to pinpoint geographic features and weather conditions more likely to generate extreme wildfires. He is Operations Node Leader in the NSW Bushfire and Natural Hazards Research Centre and is further involved in various national and international research projects. He is a regular contributor to international wildfire science and professional dialogue. Jason has been elected a Fellow of the Australian Academy of Technological Sciences and Engineering, and the Royal Society of New South Wales. He also has a background working as a firefighter with the ACT Rural Fire Service and providing operational support and expert advice to the NSW Rural Fire Service.
