Welcome to NEXUS

About
NEXUS is a five-year global research partnership funded by the UK Medical Research Council (MRC). It focuses on understanding the health impacts of non-exhaust vehicle emissions.
Non-exhaust emissions are produced by brake wear, tyre wear and road surface abrasion. These particles are increasing rapidly worldwide and remain largely unregulated, despite growing concern about their effects on human health and the environment.
NEXUS brings together researchers, policymakers, industry partners and public and patient representatives to address this critical evidence gap and support action towards cleaner, healthier air.

Our Mission
To build global research capacity and generate high-quality, policy-relevant evidence on the health impacts of non-exhaust emissions, supporting regulation, innovation and public health action worldwide.

Why Non-Exhaust Emissions Matter?
- Air pollution is the largest environmental threat to human health.
- As exhaust emissions decline, non-exhaust particles now account for a growing proportion of traffic-related air pollution.
- These particles are commonly found in urban environments and are not currently subject to robust regulatory control.
- There is limited understanding of how non-exhaust emissions affect health across different populations and settings.
What NEXUS will deliver...
Over the next five years, NEXUS will:
- Build international research capacity and shared infrastructure.
- Generate world-class evidence on exposure and health impacts of non-exhaust pollution.
- Support knowledge exchange between researchers, policymakers, industry and communities.
- Inform national and international policy and regulatory development.
- Amplify public and patient voices in air pollution research and action.
Our Network
NEXUS is a global partnership of 17 academic institutions and 8 public and industry organisations, led by the University of Oxford, Imperial College London and the University of Toronto, with patient and public involvement led by the European Lung Foundation.

Meet the Steering Group
Professor Chris Griffiths

Director of NEXUS, Professor Chris Griffiths is a leading academic general practitioner and Professor of Primary Care whose research focuses on respiratory health and the health effects of air pollution. He has led major studies examining how environmental exposures affect lung health, including the CHILL study evaluating the impact of London's Ultra Low Emission Zone on children's respiratory health. His work has influenced national and international guidelines and public health policy, particularly in relation to air quality, respiratory disease and population health.

Professor Greg Evans

Professor Greg Evans is a Professor of Chemical Engineering and Applied Chemistry at the University of Toronto whose research focuses on atmospheric aerosols, urban air pollution and traffic-related particulate emissions. He leads research developing advanced measurement technologies and observational networks to understand how particles from transportation and other sources influence air quality, climate and human health in cities. His work provides critical evidence on the sources, behaviour and impacts of particulate pollution, helping inform air quality management strategies and environmental policy decisions.

Dr Ian Mudway

Dr Ian Mudway is a Reader in Respiratory Toxicology at Imperial College London whose research focuses on understanding how air pollution and environmental exposures affect human health. His work investigates the biological mechanisms through which airborne particles influence respiratory and cardiovascular systems, combining toxicology, epidemiology and experimental studies to better understand health risks associated with air pollution. Through his research he has contributed important evidence on the impacts of particulate matter, helping to inform air quality regulation, environmental policy and public health strategies internationally.
