- Profile
-
Kathy (Katerina) Christofidou joined the Department of Materials Science and Engineering in 2019 as a Lecturer in Metallurgy. Since joining the Department, Kathy has also been appointed the Technology Platform Lead for Materials Discovery and Prototyping for Royce at the University of Sheffield, a Partner of the Henry Royce Institute.
Prior to this, she held roles at The University of Cambridge, as part of the Rolls-Royce University Technology Centre, and The University of Manchester, where she also worked in close collaboration with the Henry Royce Institute.
She holds a PhD in Metallurgy from The University of Cambridge and an MEng in Aerospace Materials Engineering from Imperial College London.
- Research interests
-
Kathy's research focuses on multiple facets of high-temperature physical metallurgy, alloy design and manufacturing.
As part of her collaboration with Rolls-Royce PLC, she has developed new polycrystalline Ni-based superalloys for turbine disc applications, as well as exploring strategies for the design of high-temperature materials amenable to laser-based additive layer manufacturing.
In addition, a major area of her research interests is that of high entropy alloys and the possibilities that these materials offer for expanding our understanding of physical metallurgy beyond a single base element and the associated thermodynamic principles governing this behaviour.
