Research interests

Jonathan Cullen's research aims to characterise physical efficiency limits for energy devices and systems and provide a consistent framework for evaluating energy demand reduction options and emissions abatement strategies. This research makes use of in-depth analysis of energy systems and specialised integrative tools, while maintaining a broad awareness of the technical options to improve energy systems. Examining specific energy technologies within the context of the whole energy system will release the potential of technical innovation, provide new tools to evaluate the wider environmental consequences of energy technologies, and help to identify opportunities for future research.

Strategic themes

Energy, transport and urban infrastructure

University Lecturer in Energy, Transport and Urban Infrastructure; systems view of energy demand covering transport, buildings and industry; frameworks for prioritising action to reduce energy demand and climate change emissions.

Inspiring research through industrial collaboration

Mapping energy and resource demands for products, companies and industries, e.g. Emerson, Siemens.

Research projects

WellMet2050, Foreseer, InDemand, WholeSEM

Jonathan Cullen is a University Lecturer in Energy, Transport and Urban Infrastructure at the University of Cambridge and a Fellow of Fitzwilliam College. Jonathan graduated with a first class degree in Chemical and Process Engineering from the University of Canterbury (NZ), and after 5 years working in industry and 5 years development work in Peru, moved to Cambridge for the MPhil in Engineering for Sustainable Development. He then completed a PhD with the title Engineering fundamentals of energy efficiency before taking up the role of Research Associate on the WellMet2050 project: a 5-year, 8-person research programme exploring all options to reduce carbon dioxide emissions from the production of steel and aluminium goods.
