- Profile
-
I hold a BEng in Metallurgy and a PhD in Solidification from the University of Sheffield. After a brief spell in industrial R&D at T&N Technology I returned to Sheffield to work on Nanostructured Soft Magnetic Materials with Professor Hywel Davies, with two further Post-Doctoral positions at TU-Delft at the Netherlands Institute for metals Research and then CENIM in Madrid. I joined the University of Sheffield as a Lecturer in 2003 and have built the AM activity here since. I was elected a Fellow of the Royal Academy of Engineering in 2023.
