Profile: Dr Alexander Goodall is a Royal Academy of Engineering Research Fellow at the University of Sheffield, conducting research into additive manufacturing of functional materials for use in high-power density electrical machines. His interests vary from fundamental material process-property relationships, to the optimisation of electrical machine topology, spanning a broad cross discipline scope. The majority of his work focusses of soft magnetic materials, however future work will also focus on conductive materials. Alex has previously worked as a lecturer at the University of Edinburgh. Alex completed his PhD at the University of Sheffield, after 5 years of experience as a design engineer in the automotive industry.
