Biography:

Prof. Cathie  Rae, is Professor of Superalloys in the Department of Materials Science, University of Cambridge,  based in the Rolls-Royce University Technology Centre. Her work focuses on high temperature alloys relating mechanical properties to microstructure, the development of single crystal superalloys, oxidation, properties of coatings and grain boundaries including recrystallization and discontinuous precipitation. She has specific expertise in the Transmission Electron Microscopy, specifically the identification and precipitation of phases and the deformation mechanisms of superalloys.  She has over 100 publications, and is Director of the Rolls-Royce Strategic Partnership Doctoral Training Centre currently training over 100 graduate students in three universities in the UK.  She has been a Royal Society Industrial Fellow and sat on the Royal Society Committee for Science Industry and Translation.
