Professor of Sustainable Engineering, Department of Engineering, University of Cambridge

Jonathan Cullen is the Professor of Sustainable Engineering at the University of Cambridge and the current President of Fitzwilliam College. He leads the Resource Efficiency Collective (www.refficiency.org) and has a reputation for top-down studies of resource systems, bringing skills in developing new metrics to reflect both energy and material consequences of materials production.

Jonathan studied Chemical and Process Engineering at the University of Canterbury, New Zealand. After 10 years working in industry and in development work in Peru, he moved to Cambridge for the MPhil in Engineering for Sustainable Development, then completed a PhD on the Engineering Fundamentals of Energy Efficiency.

Jonathan currently leads C-THRU: carbon clarity in the global petrochemical supply chain (VKRF, US$4m). He is a co-investigator on: S2uPPlant: Smart Sustainable Plastic Packaging from Plants (UKRI, £1m), TransFIRe: Foundation Industries Research and Innovation Hub (UKRI, £4.7m), UK FIRES: Locating Resource Efficiency at the heart of Future Industrial Strategy (EPSRC, £5.2m), CCG: Climate Compatible Growth (FCDO, £38m). He is a Lead Author for the IPCC AR6 Industry Chapter, an Expert Adviser to the IEA Technology Roadmaps, and co-authored the book Sustainable Materials: with both eyes open, which pioneered the concept of material efficiency for energy-intensive industries.
