Dr Marc Masen is Reader in Tribology and Mechanical Engineering Design in theDepartment of Mechanical Engineering, Imperial College London. He is the AcademicLead in Mechanical Engineering Design. His expertise includes the response of materials tomechanical contact and interaction, with a special focus on materials showing nonlinear and complex behaviour; such as polymers, elastomers, greases, and biologicaltissue. He designs, builds, and adapts advanced tribometers to gain new insights intothe behaviour of these materials. Within the Tribology research group, he collaboratesclosely with a range of companies, including SMEs and multinationals such as L'Oréal,Shell and SKF. He is the co-editor of the journal Biotribology and sits on the editorialboard of Proceedings of the Institution of Mechanical Engineers Part J - Journal ofEngineering Tribology. He teaches on a range of modules, including MechanicalTransmissions, focusing on machine elements such as shafts, gears, bearings andcouplings.
