We regularly collaborate with research groups across Australia and the world to produce high-impact, large-scale evidence that informs policy and healthcare. We have particularly strong relationships with mainland China, where there is a strong shared interest in air quality research.

There is growing interest among researchers in PM1 air pollution, or particulate matter with an aerodynamic diameter <1 μm. This fine particulate air pollution is a major component of PM2·5. However, measurement of PM1 is limited over the world. We are collaborating with the Chinese Academy of Meteorological Sciences, Chinese Academy of Sciences, University of Queensland, University of Twente, and Jinan University to predict PM1 concentration throughout China using machine learning method that leverage satellite data, monitoring data, weather data and land use information.

We will work with other relevant organisations to match the predicted PM1 data with health data to examine its health impacts. These organisations include Peking University, Sun Yat-Sen University, China CDC, Wuhan University, Zhengzhou University, China-Japan Friendship Hospital, and Shanghai Jiaotong University. Health outcomes to be measured include preterm birth, diabetes, cardiovascular health, respiratory health, dementia, autism, asthma and others.

Global climate change has caused serious health outcomes. However, evidence from numerous studies cannot be compared because of different research methods. We’ve developed an international collaboration involving more than 30 countries to systematically assess the health impacts of climate change.
