Dr Huw Woodward is a Research Fellow at the Centre for Environmental Policy. His research interests include air quality exposure and impacts on human health, the nitrogen cycle and the impact of atmospheric nitrogen on natural habitats, future land use and agriculture, and dealing with uncertainties in environmental modelling. 

Huw is a member of the Integrated Assessment Unit (IAU) and works on the Support for National Air Pollution Control Strategies (SNAPCS) project, supporting the Department for Environment, Food and Rural Affairs (Defra) in their development of UK air quality policy, including the setting of targets for harmful PM2.5 concentrations by 2040 as required by the Environment Act 2021. Huw leads the IAU's work on uncertainty analysis, ecosystem impacts of air pollutants and future UK land use.

Huw has expertise in a broad range of air quality modelling methods, including local-scale computational fluid mechanics and Gaussian plume modelling, and national scale policy-orientated modelling of population exposure. 

Huw completed his PhD in fracture mechanics at the University of Manchester where he developed a method for modelling the propagation of cracks in structures.
