Dr Peter Barbrook-Johnson

Departmental Research Lecturer in the Economics of Environmental Change


Dr Pete Barbrook-Johnson is a Senior Research Associate at the Institute for New Economic Thinking and the Smith School for Enterprise and the Environment at the University of Oxford. Pete's core research interests sit at the crossroads of social science and economics, complexity science, and environmental and energy policy. He uses a range of methods in his research including agent-based modelling, network analysis, and systems mapping. He regularly uses these, and other methods, to explore applied social, economic, and policy questions, and to support complexity-appropriate policy evaluation, but is equally interested in more theoretical aspects of complex adaptive systems.

He has conducted research with and for the likes of UK government departments/agencies such as Defra, BEIS, the Environment Agency, and the Health and Safety Executive; and businesses such as Anglian Water and Mott Macdonald. Internationally, he has collaborated with, and/or produced research for, the eThekwini Municipality Government (Durban, South Africa), the Emilia-Romagna Regional Government (Italy), and CGIAR centres in Ethiopia.

Pete is also a member of the Centre for the Evaluation of Complexity Across the Nexus (CECAN) and a Visiting Fellow at the Centre for Research in Social Simulation (CRESS) and Department of Sociology at the University of Surrey. Previously, Pete was a UKRI-ESRC Innovation Fellow and Senior Research Fellow working on public-private partnerships and collaboration, a 'Knowledge Integrator' in CECAN, a Research Fellow at the Policy Studies Institute, and a PhD student and then Research Fellow at CRESS. Prior to his PhD, Pete studied Economics at the University of East Anglia, before completing his MSc in Environmental Technology (specialising in Environmental Economics and Policy) at Imperial College London.
