Profile

Andrew Sherry is Director of the Materials Performance Centre and the Nuclear Engineering Doctorate Centre at The University of Manchester. He obtained his PhD in the Materials Science Department at The University of Manchester on the high temperature fracture of nickel-based superalloy single crystals. He joined the United Kingdom Atomic Energy Authority in 1987, working in the Engineering Metallurgy Group at Risley. He continued to work at Risley through the formation of AEA Technology and Serco Assurance where he led research in materials ageing, structural integrity. He joined The University of Manchester in 2004.

Andrew has wide experience of assessing and predicting the performance of materials used within the nuclear industry, working in the field of structural integrity alongside experts at British Energy, BNFL, Rolls-Royce, HSE and MoD for 20 years. He is active in teaching and research, is active in a number of expert panels and provides advice on materials-related issues to industry and government within the UK and Europe. He has provided input to European Structural Integrity Society (ESIS) Technical Committees on testing, numerical modelling and residual stresses and is a member of the Steering Committee of the European Network for the Evaluation of Steel Components (NESC).
