Gavin Harper helped to establish the University of Birmingham’s Centre for Strategic Elements and Critical Materials, the UK’s first centre dedicated to the study of the challenges around materials criticality. He is currently a Research Fellow with the UKRI Interdisciplinary Centre for the Circular Economy of Technology Metals and was previously a Faraday Institution Research Fellow on the ReLiB (Recycling and reuse of Lithium Ion Batteries) Project. Recent work has been focused on the circular economy of the materials used in Electric Vehicles with “Recycling Lithium-Ion Batteries from Electric Vehicles”, appearing in the 150th Anniversary Issue of Nature and a Policy Forum piece on the “Global Implications of the EU Battery Regulation” appearing in Science. He was also a Commissioner on Sir John Beddington’s University of Birmingham Policy Commission “Securing Technology Critical Metals for Britain” and is a member of the International Energy Agency’s Task 40 Group on Critical Raw Materials for Electric Vehicles. He has recently written for the journal "American Affairs" and "The Conversation" on the Impact of Russia's War in Ukraine on Critical Materials supply chains and the challenges that this presents for clean innovation.
