Systems thinking, complexity economics, social science, energy and environmental policy
UCL + Oxford
Understanding
social, economic, and policy worlds using complexity and systems science
Informing energy and environmental policy, evaluation, and governance

Hi, I'm Pete...
I am a social scientist, economist, complexity scientist, and systems thinker. I regularly use research methods such as agent-based modelling and systems mapping in my applied environmental, energy, and public health research and policy analysis. I teach on a range of undergraduate and masters courses, focussing on economics, the knowledge economy, the economics of environmental change, and the use of complexity and systems sciences in environmental issues.
You may find some of my recent work interesting, personal highlights are:
You can find an up-to-date list of my publications on my Google Scholar page.
I am currently a Lecturer in Social Economics in the Arts and Sciences department at UCL and a Teaching Associate at the Environmental Change Institute, University of Oxford. I am an Associate of the Institute for New Economic Thinking at Oxford, and a member of the Centre for the Evaluation of Complexity Across the Nexus (CECAN).
Previously, I was a Departmental Research Lecturer in the Economics of Environmental Change at the University of Oxford. I was also the Deputy Director of the NERC-funded Agile Initiative, and the Technical Modelling Lead for the UK government EEIST project. Prior to that, I was a Senior Research Associate at Oxford, and a Senior Research Fellow and ESRC Innovation Fellow at the University of Surrey (based in CECAN and CRESS, both in the Department of Sociology). I have also been a Research Fellow at the Policy Studies Institute and regularly undertake consultancy work for the public and private sectors. I completed my PhD in agent-based modelling at the University of Surrey in 2014.
I live in London, have three kids (!!), enjoy cycling, and am a vegetarian.
I am always happy to talk about any of the subjects above, or explore new opportunities for collaboration, get in touch at p.barbrook-johnson@ucl.ac.uk
-
My book on systems mapping, a practical guide written with my long-term collaborator and friend, Dr. Alexandra Penn.
-
A library of new economic modelling case studies. I led the production of this large report with colleagues from China, India, Brazil, the EU, and UK. It presents a range of new economic modelling approaches being used to understand and inform policy on the energy transition.
