Professor of Transport, Energy & Climate Change, University of Oxford

I am an interdisciplinary environmental scientist, physicist and geographer with 25 years research experience in academic and consultancy environments. I am Professor of Transport, Energy and Climate Change at the University of Oxford’s Transport Studies Unit and Environmental Change Institute.

My main research interests revolve around:
- the development and use of low carbon scenarios and transitions pathways to inform transport and energy policy
- the role of active travel in meeting public health and climate change goals, and
- design and evaluation of policy to meet net zero ambitions

Over the past 20 years I have been principal or co-investigator on research projects worth over £20 million. This includes as Co-Director of the UK Energy Research Centre, where I am leading projects on energy-transport systemic change and road transport decarbonisation pathways. I also lead a major project in the Centre for Research on Energy Demand Solutions on transport demand and energy systems modelling. I am honoured to lead ground-breaking research on evaluating the health, carbon and mobility impacts of active travel interventions, working with British, European and global partners such as the World Health Organization. New initiatives include research on Climate Compatible Growth programme for the Foreign and Commonwealth Development Office, light electric vehicles for energy demand reduction for UK Research and Innovation, and air quality impacts of net zero for National Institute for Health Research.

I am author of 50 peer reviewed journal papers, and over 30 book chapters and technical reports. I serve on the board of the WHO Health Economic Assessment Tools for Walking and Cycling.
