Clare Walter is public health PhD candidate at the University of Queensland, researching the health impacts of air pollution in Australia and the associated policies designed to mitigate the impacts. She is an honorary researcher of the University of Melbourne and a member of the Australian-German climate college. Previously based at the PeterMac lung cancer clinics as a specialist pharmacist, Clare’s advocacy work began in response to the growing number of lung cancer patients with no smoking history, and the categorisation of diesel exhaust as a group 1 carcinogen. Clare has led a number of national meetings coordinating health and science experts involved in research and policy advocacy, most recently coordinating the national expert position statement on criteria pollutants under current federal review. Clare has authored numerous government submissions on behalf of Peter MacCallum Cancer Centre, The Lung Foundation, and the University of Melbourne. Peer reviewed publications include a review of the health impacts of bushfire pollution, and the siting of childcare centres on major roads in Victoria. Regular engagement with affected communities has led to involvement in government panel hearings for large state projects and smaller local governance issues. Clare is the co-chair of the Health Special Interest Group of the Clean Air Society of Australia and New Zealand (CASANZ), a member of the Thoracic Society of Australia and New Zealand (TSANZ) and the Public Health Association of Australia (PHAA).
