Always approachable and supportive.
Professor Geraint Jewell is a Professor in the School of Electrical and Electronic Engineering at the University of Sheffield, where he obtained his BEng in 1988 and PhD in 1992 from the Department of Electronic and Electrical Engineering. He has been a member of the academic staff since 1994, serving as Lecturer for Aerospace Engineering and holding key leadership positions including the Faculty of Engineering’s first Director of Research and Innovation from 2008 to 2011, Head of the Department from 2013 to 2019, Director of the Rolls-Royce University Technology Centre in Advanced Electrical Machines since 2006, and Director of the EPSRC Future Electrical Machines Manufacturing Hub since 2019. Jewell held an EPSRC Advanced Research Fellowship from 2000 to 2005 and a Royal Society Industry Fellowship at Rolls-Royce from 2006 to 2008. In 2022, he was elected a Fellow of the Learned Society of Wales.
His research specializations encompass power dense electrical machines for aerospace applications, linear electromagnetic actuators, electromagnetic modelling of novel devices, electrical machines including permanent magnet, switched reluctance, and synchronous reluctance types, linear actuators, high-temperature devices operating up to 800°C, demonstrator starter-generators for aero-engines, and core loss calculation methods for electrical machines. Much of this work has been conducted in collaboration with Rolls-Royce. He has supervised some 20 PhD students to completion across electromagnetic and electromechanical topics. Key publications include 'A general framework for the analysis and design of tubular linear permanent magnet machines' (IEEE Transactions on Magnetics, 1999), 'Analytical modeling and finite-element computation of radial vibration force in fractional-slot permanent-magnet brushless machines' (IEEE Transactions on Industry Applications, 2010), 'Multiphase flux-switching permanent-magnet brushless machine for aerospace application' (IEEE Transactions on Industry Applications, 2009), 'Hybrid-excited flux-switching permanent-magnet machines with iron flux bridges' (IEEE Transactions on Magnetics, 2010), 'Influence of remote laser cutting on magnetic loss and mechanical properties in 0.2 mm silicon steel' (Journal of Magnetism and Magnetic Materials, 2024), and 'Thermal Failure of Stator Winding Insulation and Useful Life Assessment by Impedance Spectroscopy' (IEEE Transactions on Industry Applications, 2026).
