Biography
Dr Paul Spencer joined the IRC Polymer Engineering Laboratories in 2005, having previously worked in the Mechanics of Materials Group at Leicester University. His background is in Computational Solid State Physics, gaining his PhD from Loughborough University. Recently he has been working on a variety of academic and industrially-led research projects involving experimental and Finite Element investigations of polymeric materials at large deformations.
