The impact of air pollution on respiratory health.

We explore how air pollution and smoke affect our lungs at a cellular and molecular level.

Key Areas of Research

• Wood and Biomass Smoke
  Oliver’s team has shown that smoke from wood and other biomass fuels can damage lung cells in much the same way as cigarette smoke. Their studies reveal that these particles trigger inflammation and even promote scarring in the lungs — a process linked to chronic lung diseases such as COPD.

• Particulate Matter (PM₂.₅ and PM₁₀)
  His laboratory has investigated tiny airborne particles produced by traffic, bushfires and industry. Even at low levels, these particles can disrupt how our cells produce energy, trigger inflammation, and set the stage for long-term respiratory problems.

• Bushfire Smoke and Public Health
  During major fire events, Oliver’s group has measured the health impact of bushfire smoke on communities. Their work shows that exposure can be equivalent to smoking dozens of cigarettes, especially dangerous for children, the elderly, and people with pre-existing health conditions.

• Mechanisms of Harm
  Much of his research digs into the “how.” By studying human lung cells and experimental models, his group has linked air pollution to oxidative stress, mitochondrial dysfunction, and systemic effects that go beyond the lungs, affecting the heart and other organs.

• Generational Effects
  More recent studies explore how maternal exposure to air pollution during pregnancy may influence the health of children later in life, pointing to cross-generational risks.

Why It Matters

Our work highlights that air pollution — whether from traffic, industry, bushfires, or household wood fires — is not just a nuisance but a direct threat to health. His research provides evidence for stronger air quality standards and better protection for vulnerable communities.
