Dr Digby Symons was a Lecturer in the Cambridge University Engineering Department and a Fellow of Peterhouse until the end of 2016 and is now an Associate Professor at the University of Canterbury in New Zealand. Dr Symons is a Chartered Engineer and a Member of the Institution of Mechanical Engineers. After graduation from the University of Cambridge Dr Symons was employed as a structural engineer by Buro Happold Consulting Engineers. He later moved to the Department of Engineering Science at the University of Oxford to carry out research supported by Rolls-Royce Plc. Dr Symons was awarded a D.Phil. in 1998 for his work on composite materials. He then returned to industry to work for Cambridge Consultants Ltd., and later Weston Medical Plc., on the design and development of medical devices before taking up a position as a University Lecturer at the end of 2002. Dr Symons worked initially within the Structures Group, before transferring to the EDC in 2005. Dr Symons is interested in the appropriate application of engineering science in the design of products. His main technical area is solid mechanics with a developing interest in fluid and particulate mechanics. Domains of work have included centrifugal filters, renewable energy, timber construction, lattice materials and medical devices.
