Professor Julian Allwood worked for 10 years for Alcoa, prior to developing an academic career, initially at Imperial College, and from 2000 in Cambridge. In parallel with developing new manufacturing technologies for shaping metals, he has built up a research group looking at environmental systems and production. From 2009-13 he held an EPSRC Leadership Fellowship, to explore ‘material efficiency’ – delivering material services with less new material. This led to publication in 2012 of the book “Sustainable Materials: with both eyes open” which can be read online

In 2013 he became director of the UK INDEMAND Centre, one of six national centres looking at energy demand reduction in the UK, with a focus on industry. He also leads the inter-disciplinary BP funded Foreseer programme looking at future resource stress, the NERC funded Hosana project looking at mitigating mineral criticality, the EPSRC funded Precision Guided Flexible Forming project on new metal forming technologies, and is a co-leader of the EPSRC funded WholeSEM project developing national whole-systems energy models for the UK. In total these projects have attracted funding of £18m and employ around 60 people at nine universities, around one third of them working with Julian in Cambridge. 

Julian was a Lead Author of the 5th Assessment Report of the IPCC with a focus on mitigating industrial emissions, is chairman of the metal forming section of the International Academy of Production Engineering CIRP, and joint editor-in-chief of theJournal of Materials Processing Technology.
