Working towards a vision of pollution-free urban and rural environments, our focus is to understand the impact of both conventional and emerging air pollutants from transport, industrial and non-vehicle sources, air quality, public health and the built infrastructure.

We are looking at developing engineering driven solutions and regulatory strategies for their mitigation by means of advanced measurements and modelling techniques.


The key aims of our research is to:

  • Understand the impact of air pollution, natural hazards and climate change on health and wellbeing, and the built environment
  • Develop internationally-validated engineering-driven solutions
  • Underpin regulatory policies and strategies
  • Set the agenda for future research.

  • Quality and rigour
  • Teamwork and innovation
  • Trust and confidence
  • Confidentiality and impartiality
  • Inclusiveness.

  • Carry out fundamental research and apply it to specific global challenges
  • Capitalise on emerging technologies
  • Develop and use advanced modelling tools and approaches
  • Undertake advanced monitoring
  • Acquire high quality robust data
  • Disseminate widely and effectively.
