Chris joined the department at the start of 2013 as head of the Natural Materials Group, holding an EPSRC Early Career Fellowship. After this he then went onto co-ordinating FLIPT, a large European consortia as part of a H2020 FET Open project and has been promoted to a Senior Lecturer.
Previously he was at Oxford where he undertook his BA in Biological Sciences, MSc in Integrative Biosciences, D. Phil and later a Fellowship By Examination (a.k.a JRF) whilst working in the Oxford Silk Group.
2000-2003 BA(Hons) Biological Sciences, University of Oxford

2004-2008 D.Phil Silk Rheology, University of Oxford
- Research interests
Chris’ research uses tools developed for the physical sciences to better understand nature’s materials, from latex to collagen but with a focus on silk. By investigating unspun silk’s flow properties he has been able to gain unique insights into their biodiversity, structure and evolution. Additionally, this work has made important links between natural and industrial fibre processing which has lead to a fundamentally new way of designing, testing and fabricating bio-inspired materials.
Today he combines multiple instruments with rheology, from microscopes (confocal) and spectrometers (IR) to synchrotrons (SANS at ISIS and SAXS/WAXS at ESRF) in order to understand exactly how silk proteins arrange themselves into one of Nature’s most impressive materials.
