Dr Sue Impey is a materials scientist with over 30 years expertise in surface characterisation and thin oxide coatings for a range of applications.  Examples include surface protection to enhance corrosion resistance and novel applications for sustainability.  Dr Impey has conducted research in surface protection and corrosion control) for lightweight aerospace materials and steels for the building and industrial pipeline services.  Research includes development of oxide coatings and thin films for smart coating designs. These include high temperature coatings for aerospace, electrochromic, thermochromic and solar applications and ceramic thin film sensors for microelectronics, automotive and aerospace manufacturing sectors. 

Dr Impey is the academic lead responsible for the management of analytical equipment for surface and materials characterisation at Cranfield University and all resources. She provides support to the University and a service to industry in materials characterisation and failure analysis using analytical methods. She instigated and delivered (March 2021) a significant investment in scanning electron microscopy for the University for the benefit of external clients, students and staff.

A Senior Lecturer, Sue undertakes teaching and academic activities. Dr Impey has developed and directed Manufacturing Technology and Materials MSc courses since 2003 for the University supporting MSc programmes in Aerospace Materials, Advanced Materials, Applied Nanotechnology, Manufacturing Technology and Management and the level 7 Apprenticeship (Mastership) in materials process engineering.  She currently directs the Aerospace Materials MSc.
