Dr Stuart Walker

Post Doctoral Research Fellow


Stuart graduated from the University of Sheffield in 2007 with a Master’s degree in Mechanical Engineering. He then worked as a low carbon building consultant at Faber Maunsell (later AECOM). In 2010 he returned to Sheffield for a PhD in Tidal Turbine hydrodynamics. This led to a one-year EPSRC Fellowship (2014-2015) undertaken partly at the University of Florence. He subsequently worked as a research associate at the Universities of Sheffield and Derby on Structural Health Monitoring using Machine Learning, product environmental footprinting and defossilisation of small business, and an influential Plastics Research and Innovation Fund project at the University of Sheffield Grantham Centre for Sustainable Futures (2019-2020). In early 2020 Stuart also worked with the Medical Research Centre in the Gambia on a project to assess and reduce single-use plastic in clinical and wider community settings. At the onset of Covid-19, he worked with Professor Tony Ryan OBE and the UN on designing protective equipment for local manufacture and use in refugee camps. Stuart is a chartered engineer, a member of the Institute of Mechanical Engineers, and a STEM Ambassador.

TIGER project:

Stuart joined the University of Exeter in July 2020 as a Post-doctoral Research Fellow on the TIGER (Tidal Stream Industry Energiser) project. In addition to the engineering challenges of marine renewable energy, he is interested in the environmental impact and unforeseen consequences of defossilisation, renewable energy, and the move away from plastic. His current work is split between reliability assessment of tidal stream turbines to reduce the cost of energy, and the measurement of the environmental impact of low carbon energy technologies. He has written journal articles on tidal stream turbine hydrodynamics, environmental impact, and other topics, has had his research published in The Times and cited by the IPCC, and has submitted evidence to government on three occasions.
