Tel: 01509 222949
Gary has worked for Loughborough University since January 1987; initially as a member of the Surface Analysis Group of Loughborough Consultants Ltd located within the Physics Department. In 1990 this group became the Institute of Surface Science and Technology (ISST) and was later integrated within the Institute of Polymer Technology and Materials Engineering (IPTME) now the Department of Materials. He is currently a Senior Lecturer. Gary is responsible for a number of major fundamental research projects and at any moment in time manages a number of industrial consultancies.

Outline of main research interests
Gary’s research interests include the invention and development of novel surface processes and multifunctional materials which are aimed towards meeting the specific demands of industry. This research is multidisciplinary in nature, drawing from expertise in the fields of; materials, mechanical engineering, physics and chemistry.
Current studies are concerned with: the development of novel processes for optimised adhesion and corrosion resistance imparted to metals including aluminium alloys and steels and the modelling of joints to determine the lifetime of bonded structures taking into account complex loading and environmental considerations. Some prebond treatments, particularly those suitable for aerospace use have been upscaled for commercial use. Gary also has a large interest in polymer modification using nanoparticles to provide adhesives and coatings with advanced properties.
Gary is either sole or co-author of over 90 refereed journal papers in addition to numerous conference contributions:
