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.

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.

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.
