Summary

John has been an academic for over 30 years in the Mechanics of Materials Division of the Department of Mechanical Engineering and is a Professor of Mechanical Engineering.

Prior to joining Imperial in 1988, John was an SERC Research Fellow at the Cavendish Laboratory, Cambridge University where he did his first degree and PhD.

John has been successful in obtaining research grants from the UK and US Government (EPSRC, ONR, MRC & DTI/TSB), European Commission, UK and overseas companies. He is Director of the BIAM Centre, at Imperial College London and Executive Joint Director of the AVIC Centre, at Imperial College London.  His research expertise is structural integrity of materials including manufacturing and micro-structural effects. He is Associate Editor of the International Journal of Lightweight Materials and Manufacture. In 2019, John was appointed Honorary Professor of Xi'an Jiaotong University. He has published 338 journal and conference papers; contributed to 17 books, supervised 63 PhDs and 22 RAs. Examples include: impact performance of aerospace and automotive components, blast performance of laminated glass facades and composite structures, creep life of materials in power-station plant, water distribution plant and high-strain rate properties of polymers, composites and a wide range of other materials for defence applications and also for medical research.

John is currently Head of the Composites, Adhesives and Soft Solids (CASS) Group (comprising of eight academics):
