Dr Joy Sumner gained her Master's and Bachelor's degrees from the University of Cambridge. She matriculated in 2000 and spent the 2002/3 academic year at MIT in the USA as a member of the CMI exchange programme. She graduated after studying Physical Sciences (with a focus on materials science) in 2004. For her PhD, she assessed the use of several scanning probe microscopy techniques for the characterisation of semiconductors, also at the University of Cambridge. Since then she has been a post-doctoral researcher at the University of Bath before taking up a research fellowship at Cranfield University to assess material degradation in the energy sector. At Cranfield she has been promoted to Reader in Energy Materials, to pursue her research in understanding and testing materials' corrosion performance. This has addressed high temperature oxidation and corrosion in a number of materials systems. Joy is a Fellow of the Institute of Materials, Minerals and Mining as well as a chartered engineer. She is the Head of the Centre for Energy Engineering and engages with STEM outreach to schools.

Current activities

Dr Joy Sumner's work is related to the degradation mechanisms of materials used in components; most often in energy systems. Her main focus is the mechanisms of failure for steels and nickel based alloys in simulated real world environments. To achieve this, Joy is involved in several projects including recently the EPSRC-funded "Investigating Corrosion in Supercritical Fluids", the Innovate UK funded "Plastic Recycling Technology and Outputs: Enhancing Material Longevity and Product Quality for Commercialisation", the Knowledge Transfer Partnership with CorrosionRADAR Ltd, and several private industrial contracts. Her STEM outreach, "MATERIALS: MATERIals for Active Learning in Schools", is supported through the RAE's Ingenious scheme.

Her previous projects have included:

EPSRC funded Supergen PLE

EPSRC funded Flex-E-Plant


TSB funded CASET
