RESEARCH SUMMARy
Expertise
Landscape fire
Smoke pollution
Remote sensing
Environmental epidemiology
Research Themes
Grant's research aligns to the University's research themes of Better Health and Environment, Resources and Sustainability, including the increasingly recognized nexus between the fields of human health and landscape ecology. Grant's current research into biomass smoke aims to improve our estimates of human exposure to the fine particulate pollution produced by landscape fires and wood heater usage. Smoke exposure can have significant impacts on human health for sufferers of asthma and cardio-vascular diseases, and biomass smoke is a significant contributor to atmospheric aerosol load in south-eastern Australia, where humans live in close proximity to vegetation that experiences significant wildfires in the summer, and undergoes prescribed burning to reduce fire risk in winter. In order to better understand the link between smoke exposure and human health impacts, we need improved models of smoke emissions from biomass burning, and smoke transport patterns. Grant is utilizing remotely-sensed data and geospatial modelling methods to improve empirical models of smoke exposure and physical atmospheric transport models, to better inform this epidemiological research.
Grant's research interests also include adapting real-time environmental data sources and the computing cloud to improve ecological and health knowledge. Grant has developed a real-time Forest Fire Danger Index map adopted by the Tasmanian Fire Service, a heat-wave warning system for the Tasmanian Department of Health and Human Resources, and is a lead developer on the AirRater air pollution and pollen alert app project.
Collaboration
Grant has previously collaborated with NASA and South Dakota State University on a project understanding the dynamics of fire weather and occurrence using remotely sensed data. He was involved in the Fire and Vegetation team of the NERP Landscapes and Policy Hub, a multidisciplinary project involving the University of Tasmania, the Australian National University, Murdoch University, Griffith University and Charles Sturt University. Grant is currently working on the 'Bushfires, smoke and people' ARC linkage grant, a large project involving the University of Tasmania, the British Columbia Centre for Disease Control, the Bushfire CRC, the CSIRO and a number of state Environmental Protection Authorities. He is also collaborating with the CSIRO and Victorian health authorities in modelling human exposure to smoke from the 2014 Hazelwood coal mine fire, and in developing the AQVx air quality visualization platform. He is currently work package co-leader with the NSW Bushfire and Natural Hazards Research Centre.
