Professor Paul Withey

School of Metallurgy and Materials
Professor of Casting Technology

Paul Withey is Professor of Casting Technology.

Paul joined academia in 2018 and in 2019 was awarded an EPSRC Manufacturing Fellowship. He is working with industry to deliver improved casting technology for a number of different applications.

Paul is also knowledgeable about the DeHavilland Comet investigation in the 1950s and has shared his enthusiasm both in talks and documentaries.


  • PhD in Metallurgy and Materials University of Birmingham, 1989
  • BSc in Physics, University of Birmingham, 1986


Paul Withey qualified with a BSc (Hons) in Physics from the University of Birmingham in 1986. He went on to study for a PhD in magnetic materials in the School of Metallurgy and Materials in 1989.

Following a period in academia where Paul moved into the casting field, he moved to Rolls-Royce in 1994 initially in the research foundry in Bristol and latterly based in the production facility in Derby.

Paul worked on both production methods, yield improvement and new technology and in 2005 he became the Associate Fellow in Casting Technology.

In 2018 Paul returned to Birmingham to continue his academic career, focussing on casting technology.
