Dr Grant Williamson is a landscape and fire ecologist and spatial analyst at the University of Tasmania. He completed his doctorate at the University of Adelaide, studying the impact of fine-scaled rainfall regime across a climate gradient on adaptation in native Australian grasses. He undertook a post-doctoral position at Charles Darwin University in an ARC-linkage project examining the impact of mosquito control measures on mosquito-borne disease in humans and the ecology of mangrove swamps. In 2008, he moved to the University of Tasmania for a post-doctoral role on the ARC-linkage Biomass Smoke Project, investigating the effects of smoke pollution from landscape fires on human health and developing predictive models for smoke exposure.
During his time at the University of Tasmania, Dr Williamson contributed to the NERP Landscapes and Policy hub, researching landscape-scale human-ecological interactions in the Australian Alps and Tasmanian Midlands. In 2014, he received a post-doctoral scholarship from the Centre for Air Quality and Health Research and Evaluation at the University of Sydney to further his work on human exposure to smoke pollution from landscape fires. He currently serves as a Senior Research Fellow and works with the NSW Bushfire Risk Management Research Hub, developing modelling tools to understand fire history, shifts in Australian fire regimes and vegetation under climate change, and improvements to prescribed burn planning. He holds the position of Associate Professor in Physical Pyrogeography and serves as Deputy Director of the Fire Centre.
